The answer to that question is the sum of the hours he studied for on both days, which will be 1/4 + 3/8.

However, we cannot add fractions with different denominators. In this case, it's 4 and 8.

So if we want to add them, we must make the denominators similar to each other. How to make 4 into 8? We multiply it by 2: 4 x 2 = 8.

BUT when we multiply fractions, we must multiply both the numerator and the denominator by the same number to keep its original value. In this case, if you want to multiply 4 by 2, you must also multiply 1 by 2.

=> SO to make 1/4 into y/8, we will multiply it like this (1 x 2) / (4 x 2) = 2/8

Now we can add the 2 fractions together. 2/8 + 3/8 = (2 + 3)/8 = 5/8. THIS IS YOUR ANSWER.

TL;DR: He studied 5/8 (or 0.625) hour altogether on both days.

in gym class, you run 3/5 mile. your coach runs 10 times that distance each day. how far does your coach run each day?
Feliz [49]
The coach runs 6 miles each day. Because you would do 3 divided by 5, and get 0.6. Then times that by 10 and you get 6.

Answer:

see below

Step-by-step explanation:

f(x) = 5x^3 +1, g(x) = – 2x^2, and h(x) = - 4x^2 – 2x +5

f(-8) = 5(-8)^3 +1 = 5 *(-512) +1 =-2560+1 =-2559

g( -6) = -2 ( -6) ^2 = -2 ( 36) = -72

h(9) = -4( 9)^2 -2(9) +5 = -4 ( 81) -18+5 = -324-18+5=-337

Pls help! I need help with a and c I did b already!
laila [671]

Answer:

A= y= -2x+7.

B= y= -\frac{3}{2}x+ 6

Step-by-step explanation:

The linear equation is y=mx+b

A= y= -2x+7.

-2 represents he slope and 7 represents the y intercept.

B= y= -\frac{3}{2}x+ 6

-\frac{3}{2} is the slop and 6 is the y intercept.

Hope this helps :)
