Answer:

32

Step-by-step explanation:

Suppose Alvin is x years old. Then Elga is x+15 years old.

x+x+15=49

2x=34

x=17

17+15=32

Answer:

assume: f(x) = A(bx); then: f(8) = A(b8) = 20;

and: f(2) = A(b2) = 5

dividing the first equation by the second equation gives: b6 = 4; or: b = 4(1/6) = 1.26;

then: A(1.262) = 5; or: A = 5/(1.262) = 3.15; then: f(x) = 3.15(1.26x);

so that: f(25) = 3.15(1.2625) = 1017.6 ---> 1018

Step-by-step explanation:

Answer:

I'm guessing when it says "over the y-axis", it means to reflect it over the y-axis.

In that case, you would graph the points of the triangle, then flip them over the y-axis (change the x-values).

ex. R(-5,3)-R`(5,3)

Answer:

c. 9t+45 that shows distributive property

where it shows a*(b+c)=(a*b)+(b*c).so,9(t+5)=9*t+9*5

Answer and explanation:

The connection of the rope from the stake to the pole will form a triangle so that one side is the hypotenuse(the rope), another is the opposite side(the pole) and the other is the adjacent side(the distance from the stake to the pole).

The unknown side is the adjacent side which is the distance from the stake to the pole. To find an unknown side in a triangle in this form, we use the Pythagorean theorem.

Therefore c²=a²+b²

c=20ft

a= 7ft

b= unknown

So we use the formula to find unknown side(distance from stake to base of pole)

20²=7²+b²

400=49+b²

b²=400-49

b²= 351

b=√351

b= 18.735ft

Therefore distance from stake to base of pole = 18.735 feet

Answer:

x

=

0, 1/3

x=x^3-x/2-9

Step-by-step explanation:

Answer:

19

Step-by-step explanation:

1. Both angles would probably add up to 180 degrees.

2. So rewrite this as an equation. (2x + 3) + (9x - 32) = 180

3. Add up like terms like 2x and 9x which would be 11x

4. Rewrite equation again for less confusion. 11x + 3 - 32 = 180

5. Combine like terms again. Like terms this time are 3 and 32

6. 3 - 32 which would be negative 29

7. Rewrite equation again for less confusion. 11x - 29 = 180

8. Add 29 to both sides of equation meaning add 29 to 180.

9. You're left with 11x = 209

10. Divide 209 by 11

11. Lastly you get 19.

Answer:

38%

Step-by-step explanation:

[tex]\frac{Part}{Whole}[/tex] × 100%

500 - 310 = 190

[tex]\frac{190}{500}[/tex] × 100% = 38%

Step-by-step explanation:

Slope-intercept format:

y = mx+b

m = slope

b = y-intercept

Now we plug it in to get the equation:

y=-3x-1

Answer: £60

Step-by-step explanation:

Natalie bought a pair of shoes for £54 which had been reduced by 10%.

To find the original cost, assume the original cost is x.

The discount would be: 10% * x

The expression would therefore be:

x - (10% * x) = 54

x - 0.1x = 54

0.9x = 54

x = 54 / 0.9

x = £60

Step-by-step explanation:

Answer: LA Galaxy has won 24 of their soccer matches.

Step-by-step explanation:

To find 60% of 40, you can multiply 60/100 by 40.

60/100 x 40 = 24.

In conclusion, LA Galaxy has won 24 of their soccer matches.

Answer:

Length, l = 10 m, breadth = 8 m

Step-by-step explanation:

Let l be the length and b be the width of the rectangle.

The area of a rectangle is given by :

A = lb

80 = lb ...(1)

The perimeter of a rectangle is given by :

P = 2(l+b)

36 = 2(l+b)

18 = (l+b) ....(2)

We need to solve equation (1) and (2). On solving we get :

l = 10, b = 8

So, the dimensions of the shop is 10 m and 8 m.
