Answer:

Jenny's age = 8 yr

Sam's age = 17 yr

Step-by-step explanation:

Let x = Jenny's age now

then x + 9 = Sam's age now

x - 5 = Jenny's age 5 years ago

x + 9 - 5 = x + 4 = Sam's age 5 years ago

4(x - 5) = x + 4

4x - 20 = x + 4

3x = 24

x = 8 = Jenny's age now

x + 9 = 8 + 9 = 17 Sam's age now

Check:  5 yrs ago Jenny was 3 and Sam was 12

4(3) = 12, so the answer is correct.

5 x 2x = 10x

5 x -4 = -20

leaving 3x combine like terms

10x + 3x = 13x

form an equation

Answer:

$75

Step-by-step explanation:

150 x 0.35 = 52.50

150 x 0.15 = 22.50

(or do 50% of whole total)

22.50 +52.50 = $75

Answer:

75

Step-by-step explanation:

since he spent a total of 50% of his money (35%+15%), then 50% of 150 is 75

Answer:

5.1

Step-by-step explanation:

cos 65° = [tex]\frac{x}{12}[/tex]  

x = 12 cos 65°

cos 65° ≈ 0.422618261741

x ≈ 5.07 ≈ 5.1

Answer (assuming it can be in slope-intercept format):

[tex]y = -\frac{3}{5} x+7[/tex]  

Step-by-step explanation:

When knowing the y-intercept of a line and its slope, we can write an equation representing it in slope-intercept form, or [tex]y = mx + b[/tex].

1) First, find the slope of the equation. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to find the slope. Substitute the x and y values of the given points into the formula and simplify:

[tex]m = \frac{(4)-(7)}{(5)-(0)} \\m = \frac{4-7}{5-0} \\m = \frac{-3}{5}[/tex]

Thus, the slope is [tex]-\frac{3}{5}[/tex].

2) Usually, we would have to use one of the given points and the slope to put the equation in point-slope form. However, notice that the point (0,7) has an x-value of 0. All points on the y-axis have an x-value of 0, thus (0,7) must be the y-intercept of the line. Now that we know the slope of the line and its y-intercept, we can already write the equation in slope-intercept format, represented by the equation  [tex]y = mx + b[/tex]. Substitute [tex]m[/tex] and [tex]b[/tex] for real values.

Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{3}{5}[/tex]  in its place in the equation. Since [tex]b[/tex] represents the y-intercept, substitute 7 in its place. This gives the following equation and answer:

[tex]y = -\frac{3}{5} x+7[/tex]

Answer:

7 cups

Step-by-step explanation:

1 cup = 8 fluid ounces

7 cups x 8 fluid ounces = 56 fluid ounces

56 is greater than 53

56 > 53

Answer:

length = 20

Width = 14

Step-by-step explanation:

x - y = 6   -------------------(I)

x + y = 34 ------------------(II)

Add equation (I) & (II). So y will be eliminated and you can find the value of x

(I)         x - y = 6

(II)       x + y = 34  {Now add}

        2x      =  40      {Divide both sides by 2}

             x   = 40/2

x = 20

Plugin x = 20 in equation(II)

20 +y = 34

       y = 34 -20

y = 14

21 dollars × (1 cup)/(1.5 dollars) = 21/1.5 cups = 14 cups

Answer:

(0, 4)

Step-by-step explanation:

To find the intersection of two lines, we want to find the value when they equal each other. To do this, we want to set the equations equal to each other.

First, let's simplify y = x + 4x + 4 by combining the x's.

y = 5x + 4

Now let's set the equations equal to each other. Since they both equal y, we can set the opposite sides equal to each other.

5x + 4 = 2x + 4

Now you want to combine the terms.

[subtract 4] 5x = 2x

[subtract 2x] 3x = 0

Now you want to isolate the x.

[divide by 3] x = 0

Now we want to find y by plugging x = 0 back into the equations.

y = 5(0) + 4

[multiply] y = 0 + 4

[add] y = 4

Check this with the other equation.

y = 2(0) + 4

[multiply] y = 0 + 4

[add] y = 4

Your answer is correct!

(0, 4)

Answer:

  a)  (3, 0), (0, -2)

  b)  see below

Step-by-step explanation:

The x-intercept is found by setting y=0 and solving for x:

  2x = 6

  x = 6/2 = 3 . . . point (3, 0), x-intercept

The y-intercept is found by setting x=0 and solving for y:

  -3y = 6

  y = 6/-3 = -2 . . . point (0, -2), y-intercept

The graph is the line through these points.

Answer:

You multiply by 6 and the 5th term is 60

Step-by-step explanation:

15*4 = 60

Answer:

multiply by 4 & the unknown number is 60

Step-by-step explanation:

3×4=12

6×4=24

9×4=36

12×4=48

15×4=60

Multiplying x by any positive number smaller than 1 will result in some smaller value.

For example, if the scale factor is k = 0.5, then we can think of this as the fraction k = 1/2. Multiplying by 1/2 will make any number smaller, namely, exactly half as much.

We are taking a fractional part of the original number, so its expected the result is smaller. It's like having a whole cake and we only take slices of that cake to end up with the new value. There's no way having one or more slice be larger than the original whole amount.

Because things are getting smaller, we call this type of dilation to be a reduction or we can call it shrinking. This is in contrast to an enlargement when k > 1.

-----------------------------------------

More info (optional section)

Claim:  For some positive number k such that k < 1, we have xk < x when x is positive.

The proof of this claim is fairly straight forward.

We multiply both sides of k < 1 by x to get

k < 1

x*k < x*1

xk < x

The inequality sign does not flip because we're multiplying both sides by a positive number x.

So because xk < x, this shows that the original value x gets smaller to xk when we apply the positive scale factor k such that k < 1. This is the same as saying 0 < k < 1. Furthermore, xk < x is the same as 0 < xk < x.
