Answer:

7/4

Step-by-step explanation:

10x - 8 = 2x + 6

-2x        -2x

8x - 8 = 6

    + 8   +8

8x = 14

8      8

14/8 can be reduced to 7/4.

14/8 ÷ 2/2 = 7/4

Answer:

Dan made $37 washing cars

equation: 41 + n = 78

Step-by-step explanation:

41 + n = 78

to solve, subtract 41 on both sides of the equation:

41 - 41 + n = 78 - 41

n = 37

Answer:

let ratio 4:5 be 4x& 5x

according to the question

5x=75

x=75/5=15

the number of Maths books=4x=4×5=20 is your answer

Answer:

[tex]\sqrt{8x^{2} }[/tex]+5-3 = 8.12

8.12 rounded to nears whole number is 8

therefore 8.12 rounded down to three decimal places is 8.1

Therefore your answer would be 8.1

If it wont let you add a decimal your answer would also be 8

Answer:

70

Step-by-step explanation:

cows:sheep=6:5

sheep:pigs=2:1

cows:sheep:pigs=12:10:5

27x=189

x=7

sheep=10*7

sheep=70

Answer:

There are 84 cattle, 70 sheep and 35 pigs

Step-by-step explanation:

We're told three things:

Starting off, let's express the the last point as an equation:

c + s + p = 189

To solve this, we need to eliminate variables by substituting others in their place.  Let's start with cattle to sheep.  Using the 6:5 ratio of cattle to sheep:

c / 6 = s / 5

s = 5c / 6

Let's update our equation to match that

c + 5c / 6 + p = 189

Now to eliminate pigs. We know that there is one pig for every two sheep.  So:

p = s / 2

We can substitute our relationship with cattle to sheep in to that to express p as a function of c:

p = (5c / 6) / 2

p = 5c / 12

Now we can substitute that into the original equation

c + 5c / 6 + 5c / 12 = 189

Now we can solve for c:

c + 5c / 6 + 5c / 12 = 189

12c / 12 + 10c / 12 + 5c / 12 = 189

(12 + 10 + 5)c / 12 = 189

27c / 12 = 189

9c / 4 = 189

9c = 756

c = 84

So there are 84 cattle.  We can use the original given relationships to find the rest.

s = 5 × 84 / 6

s = 5 × 14

s = 70

p = s / 2

p = 70 / 2

p = 35

So there are 84 cattle, 70 sheep and 35 pigs

Let's double check:

84 + 70 + 35 = 189  - correct

70 / 2 = 35 - correct

5 * 84 / 6 = 70 - correct

So the answer is correct.

Answer:

uh the second step has the initial error they subtracted 3x and made 40 positive instead of adding 3x and leaving 40 negative, the first step is fine tho, the equation (i did this in my head so it miighhtt be wrong but uh) 11(3x - 4)

Step-by-step explanation:

i explained that thing but wo explaining

first step right

middle (and last bc of middle) step wrong

correct answer is 11(3x - 4)

Answer:

C. 3 eggs

Step-by-step explanation:

Mr. Niles used 5/12 of a carton of eggs to make breakfast Saturday. He used 2/12 of the carton on Sunday. How many more eggs did he use on Saturday?

A. 7 eggs

B. 4 eggs

C. 3 eggs

D. 1 egg

A carton of egg = 12 eggs

Saturday

5/12 of a carton of egg

= 5/12 × 12

= 5 eggs

Mr. Niles used 5 eggs on Saturday

Sunday:

2/12 of a carton of egg

= 2/12 × 12

= 2 eggs

Mr. Niles used 2 eggs on Sunday

How many more eggs did he use on Saturday?

= 5 eggs - 2 eggs

= 3 eggs

C. 3 eggs

Answer:

[tex]x[/tex] ≈ [tex]12\\[/tex]°

Step-by-step explanation:

Since we don't know the angle, again, we will replace it with [tex]X[/tex].

This time, we are trying to fine the angle of depression from the top. However, we are still in luck, because the angle of elevation = the angle of depression, meaning we can start from the base, and use Sine.

[tex]Sine = (\frac{Opposite}{Hypotenuse})[/tex]

[tex]sinX =\frac{208}{1000}[/tex]

[tex]X = sin^-^1(\frac{208}{1000})\\[/tex]

[tex]x[/tex] ≈ [tex]12\\[/tex]°

Answer:

C

Step-by-step explanation:

When using percentages to multiply 100% is equivalent to a factor of 1, 150% to 1.5, 15% to .15, etc.

first one:

a 60% increase indicates the future yield will be 60% + 100% or 160% of the regular yield.  All you have to do is multiply the current yield by 160% or 1.6

3. same idea: the Akashi bridge is 153% of or 1.53 times the length of the Verrazano-Narrows bridge.

4. Take the difference between the two jobs  ($880.00-$790.00=$90.00) then find what $90.00 is 12% of.

.12 x WN = $90  yields   WN= $90/.12  = amount that he will have to sell.   You can check your answer by multiplying it by .12 to get $90.

Answer:

7.59 m^2

Step-by-step explanation:

here's your solution

=> Radius of circle = 2.2 m

=> we need to find out area of semicircle

=> area = 1/2πr^2

=>. area = 1/2*3.14*2.2*2.2

=> area = 7.59 m^2

Answer:

Savings % = 40%

Monthly income = Rs 20,600

Amount spend = Rs 12,360

Step-by-step explanation:

Let the percentage savings be 's'

Percentage savings = 60% + s = 100

s = 100 - 60

s = 40%

This is because, percentages sum up to hundred (100)

Let her monthly income be I

40/100 × I = 8240

40I/100 = 8240

40I = 824000

Divide both side by 40

I = Rs 20,600

Therefore her monthly income is Rs 20,600

Amount she spends

20,600 - 8240

= Rs 12,360

Or 60/100 × 20,600

= Rs 12,360

Answer:

Step-by-step explanation:

a). Equation: m∠K + 40° + 60° = 180°

    [Since, these angles are located at a point of a straight line so they are   supplementary angles]

b). m∠K = 180° - 100°

    m∠K = 80°

c). Equation: m∠M + m∠K = 180°

   [Since, ∠M and ∠K are the supplementary angles]

d). m∠M + 80° = 180°

    m∠M = 180 - 80

              = 100°

Answer:

5

Step-by-step explanation:

Since the two sides of the triangle have equal opposite angles , they will be equal .

Since sides opposite to equal angles are equal.

Using this concept ,

=> 3x -4 = 2x + 1

=> 3x - 2x = 4 + 1

=> x = 5

Answer:

x = 5

Step-by-step explanation:

Since it is an isosceles triangle, the two opposite sides are equal.

3x - 4 = 2x + 1

3x - 2x = 1 + 4 (Put variables together and numbers together)

x = 5

3x - 4 = 3(5) -4 = 11

2x + 1 = 2(5) + 1 = 11

x + 1 = 5 + 1 = 6

Hope this helps! :)
