Answer:
21/8
Step-by-step explanation:
Simplify the following:
6 + 1/4 - (3 + 5/8)
Put 3 + 5/8 over the common denominator 8. 3 + 5/8 = (8×3)/8 + 5/8:
6 + 1/4 - (8×3)/8 + 5/8
8×3 = 24:
6 + 1/4 - (24/8 + 5/8)
24/8 + 5/8 = (24 + 5)/8:
6 + 1/4 - (24 + 5)/8
24 + 5 = 29:
6 + 1/4 - 29/8
Put 6 + 1/4 - 29/8 over the common denominator 8. 6 + 1/4 - 29/8 = (8×6)/8 + 2/8 - 29/8:
(8×6)/8 + 2/8 - 29/8
8×6 = 48:
48/8 + 2/8 - 29/8
48/8 + 2/8 - 29/8 = (48 + 2 - 29)/8:
(48 + 2 - 29)/8

Answer:
the gradient is 3
y- intercept is 4
Step-by-step explanation:
when you're asked the gradient, you can find it as a coefficient of"x" in equation where the coefficient of "y" is one.
y=mx+b
m=> gradient
b=> y- intercept
Answer:
28 inches
Step-by-step explanation:
The three pieces are in the ratio
5:7:9
Multiply each piece by x
5x : 7x: 9x
Add the pieces together
5x+7x+9x = 147
Combine like terms
21x = 147
Divide each side by 21
21x/21 =147/21
x =7
The smallest piece is 5x = 5*7 =35
The largest piece is 9x = 9*7 =63
The difference is 63-35=28
