Apiece of string is 5 5/8 inches long. how much should lena cut off to make it 3 1/2 inches long?

2 1/8 inches

Step-by-step explanation:

First, we make the fractions into improper fractions:

5 5/8 = 45/8

3 1/2 = 7/2

Now we make them to have the same denominator

7/2 = 28/8

Now we substract

45/8 - 28/8 = 17/8

17/8 =  2  1/8 inches

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
