HELP ME FASTTTTTTT !!!!!!!!!!!!!!!!!!!!!!!!!

All we need to do is get the ? by itself in both equations.

-4 - ? = - 7

-? = -7 + 4

-? = -3

? = 3

? - ( -3) = 5

? + 3 = 5

? = 5 - 3

? = 2

Answer:

First ?: 3

Second ?: 2

Step-by-step explanation:

Do the inverse operation of what is shown to get the answer.

First ?:

-4 - ? = -7

-7 + 4 = -?

-3 = -?

3 = ?

Second ?:

? + 3 = 5 (Two negatives in a row make a positive.)

5 - 3 = ?

2 = ?

I hope this helps! \(★ω★)/

Answer:

  4

Step-by-step explanation:

The slope of L1 is given by the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (5 -1)/(-2 -(-3)) = 4/1 = 4

The slope of L2 is the same as the slope of L1. The slope is 4.

Answer:

48 cm

Step-by-step explanation:

If it's square and the area is 144, then the sides are each 12cm (a = l x w, 144 = 12 x 12)

12cm x 4 sides = 48cm

Answer:

48

Step-by-step explanation:

The area is 144 cm².

A = s²

144 = s²

[tex]\sqrt{144\\}[/tex] = s

12 = s

photo frame is a square.

perimeter of a square = 4 * s

P = 4 *s

P = 4 (12)

P = 48

Answer:

x = 20

Step-by-step explanation:

4x and 5x are same- side interior angles and sum to 180° , then

4x + 5x = 180

9x = 180 ( divide both sides by 9 )

x = 20

Answer:

x = 20

Step-by-step explanation:

the two angles are same-side interior angles, thus, the two angles add up to 180°

=> 4x + 5x = 180

=> 9x = 180

=> x = 20

Answer: No, whether people over eat or never eat does not depend on their age. It naturally depends on how you ate as a kid, because if you eat alot as a kid your eating habits grow into that as you get older because your stomach has gotten used to lots of food.

Step-by-step explanation:

Answer:

Area = 228 m²

Perimeter = 60 m

Step-by-step explanation:

The figure given shows a rectangle that has a cut triangular portion.

✔️Area of the figure = area of rectangle - area of the triangular cut portion

= L*W + ½*bh

Where,

L = 20 m

W = 12 m

b = 20 - (8 + 8) = 4 m

h = 6 m

Plug in the values

Area = 20*12 - ½*4*6

Area = 240 - 12

Area = 228 m²

✔️Perimeter = perimeter of rectangle - base of the triangular cut portion

= 2(L + W) - b

L = 20 m

W = 12 m

b = b = 20 - (8 + 8) = 4 m

Plug in the values

Perimeter = 2(20 + 12) - 4

= 2(32) - 4

= 64 - 4

Perimeter = 60 m

Answer:

a = 30°

b = 11°

Step-by-step explanation:

JK = 360 - 110 - 130 - 54 = 66°

Inscribed angles = 1/2 their arc

∠K = 1/2(130 + 54) = 92°

∠J = 1/2(110 + 130) = 120°

∠M = 1/2(66 + 110) = 88°

8b = 88°

b = 11°

∠L = 1/2(54 + 66) = 60°

2a = 60°

a = 30°

Answer: $42

Step-by-step explanation:

Since the trampoline was originally priced at $100 but went on sale for 60%, the price paid will be:

= $100 - (60% × $100)

= $100 - (0.6 × $100)

= $100 - $60

= $40

Emmett bought the trampoline and then paid 5% sales tax, the total amount paid will be:

= $40 + (5% × $40)

= $40 + (0.05 × $40)

= $40 + $2.

= $42

She paid $42 in total.

5.76

Step-by-step explanation:

What is 12 percent (calculated percentage %) of number 48? Answer: 5.76.

Answer:

D. square root of 7 to the power of 3

R. b=6/8

Answer:

1) False

2) True

3) a) True b) False

4) False

Step-by-step explanation:

1)

Two-point are collinear if they lie in the same line. The vector -2AB is antiparallel to the vector AB then it is False.

2)

A unit vector could be difinede as:

[tex]\vec{u}=\frac{\vec{v}}{|\vec{v}|}[/tex]

Terefore, [tex]\frac{1}{AB}\vec{AB}[/tex] is a unit vector. It is True.

3)    

a) If AB=-3AC

The points, A, B, and C are collinear, because all of them lie in the same line. True

b) Let's take the modulus in each side.

[tex]\vec{AB}=-3\vec{AC}[/tex]

[tex]|\vec{AB}|=|-3\vec{AC}|[/tex]

[tex]|\vec{AB}|=|-3||\vec{AC}|[/tex]

[tex]|\vec{AB}|=3|\vec{AC}|[/tex]

So it is False.

4)

If we put the vector AI = 3/2 AB into the first equation we will have:

[tex]2(-\frac{3}{2}\vec{AB})+3\vec{IB}=-3\vec{AB}+3\vec{IB}[/tex]

And we can not say that it is a cero vector, so it is False.

I hope it helps you!

Answer:

B = 115

Step-by-step explanation:

Since A and B are supplementary, they add up to 180 degrees.

Thus, 65 + B = 180, and B = 115

Answer:

60

Step-by-step explanation:

The sum of two interior angles in a triangles is equal to one exterior angle that is supplementary to the third interior angle

3x+4x = 10x - 45

7x = 10x - 45 transfer 45 to the other side of equation and subtract 7x from 10 10

45 = 10x - 7x

45 = 3x divide both sides by 3

15 = x angle B is 4*15 = 60

Answer:

Step-by-step explanation:

Consider the parent function:

The graph of the function open up and the vertex is at the origin, the point (0, 0)

Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:

The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:

Since all the options have 1/20 as a coefficient, our function is:

This is option B

Answer:

[tex]p =2.5[/tex]

[tex]q = 0.5[/tex]

Step-by-step explanation:

Given

[tex]2x + 3y = 7[/tex]

[tex]( p-q ) x + (p+q) y = 3 p + q -2[/tex]

Required

Find p and q

To do this, we make direct comparison between the given expressions.

[tex]2x + 3y = 7[/tex] and [tex]( p-q ) x + (p+q) y = 3 p + q -2[/tex]

This implies that:

[tex](p - q)x = 2x[/tex]

[tex](p+q)y = 3y[/tex]

[tex]3(p + q) - 2 = 7[/tex]

So, we have:

[tex]p - q = 2[/tex] --- (1)

[tex]p+q =3[/tex] -- (2)

[tex]3(p + q) - 2 = 7[/tex] --- (3)

If [tex](1)\ and\ (2)[/tex] are true, then [tex](3)\ must[/tex] be true.

So, we only solve [tex](1)\ and\ (2)[/tex]

Add (1) and (2) to eliminate q

[tex]p+p-q+q=2+3[/tex]

[tex]2p=5[/tex]

Solve for p

[tex]p = 5/2[/tex]

[tex]p =2.5[/tex]

Substitute [tex]p =2.5[/tex] in (2)

[tex]p+q =3[/tex]

[tex]q = 3 - p[/tex]

[tex]q = 3 - 2.5[/tex]

[tex]q = 0.5[/tex]

Answer:

$1200 gross pay

Step-by-step explanation:

if you worked 40 hours normally and had 10 hours over time, that equation for the gross pay would be X = 20(40) + 30(10)

X = 20(40) + 30(10)

X = 800 + 300

X = 1200

Answer:

46080 ft²

Step-by-step explanation:

Given :

Scale :

1 in = 4 feets

Recall :

I foot =. 12 inches

Length of drawing = 4 feets

Length of drawing in inches = 4 * 12 = 48 inches

Width of drawing = 5 feets

Width of drawing in inches = 5 * 12 = 60 inches

Actual length of pool = 48 * 4 = 192 feets

Actual width of pool = 60 * 4 = 240 feets

The actual area of the pool :

Length * width

192 feets * 240 feets = 46080 ft²

Answer:

10 : 17

Step-by-step explanation:

Male runners = 35

Female runners = 50

Total runners = male runners + female runners

= 35 + 50

= 85 runners

What is the ratio of the number of female runners to the total number of runners?

Ratio of the number of female runners to the total number of runners = number of female runners : total runners

= 50 : 85

= 50 / 85

= 10/17

= 10 : 17

Ratio of the number of female runners to the total number of runners = 10 : 17

Answer:

Step-by-step explanation:

700(.04)(3)= $84

The answer is x = 4

Step 1: Simplify both sides of the equation.

3 /2 (x−6)=−3

( 3 /2 )(x)+( 3 /2 )(−6)=−3(Distribute)

3 /2 x+−9=−3

3 /2 x−9=−3

Step 2: Add 9 to both sides.

3 /2 x−9+9=−3+9

3 /2 x=6

Step 3: Multiply both sides by 2/3.

( 2 /3 )*( 3 /2 x)=( 2 /3 )*(6)

x=4

Answer:

x=4
