Answer:

8 = x

Step-by-step explanation:

all three sides are equal, so it is an equilateral triangle

if it is an equilateral triangle, each angle is 180/3 = 60 degrees

therefore

60 = 7x+4

subtract 4 from each side

60-4 = 7x+4-4

56 = 7x

divide by 7 on each side

56/7 = 7x/7

8 = x

I am greater than 54 fewer tens than 90?

Lubov Fominskaja [6]

In all cases, we will let x represent the number.
1) 54 tens = 540
90 - 540 = -450
x > -450

2) x < 36 and x > 24
24 < x < 36

3) 8 tens and 5 ones = 80 + 5 = 85
x > 85

4) x > 27
x < 33
And the value in the ones place is less than the value in the tens place, so
30 ≤ x ≤ 32
