Answer:
88 problems
Step-by-step explanation:
Set this problem up as fractions
86/x = 98/100
Cross multiply
86 × 100 = x × 98
8600 = 98x
Divide both sides by 98
87.75... = x
Round to nearest whole number
87.75 rounds up to 88

In this problem, you are asked to translate this verbal expression into algebraic expression. Then you must simply this expression if possible.So for this problem, the algebraic expression is:
1.2 ( w + u / 12) -> so simplifying this, will give us:
= 1.2w + 1.2*u/12
= 1.2w + u/10 would be the answer.
The measure of a triangle is 180 degrees. In other words the sum of the angles of a triangle is 180 degrees
To solve for x set all of the expressions of angles equal to 180 and isolate x
11x - 3 + 7x + 5 + 13x - 8 = 180
31x + (- 6 + 6) = 180 + 6
31x/31 = 186 / 31
x = 6
To find the measure of each angle plug 6 into the x into each individual expression
Hope this helped!
Answer:
D 1 and -1
Step-by-step explanation:

divided by 8

(x+1)(x+1)=0
so x=+-1
