The length of side x is a, .6
Answer:
2.28
Step-by-step explanation:
Let Sarah's age be s and Antonio's age be a.
According to your question,
2a + 3s = 34
s = 5a
substituting the value of s in eq. 1,
2a + 3(5a) = 34
= 2a + 15 a = 34
17a = 34
thus, a = 34/17 = 2
substituting the value of a is s,
s = 5(2)
= 10
Thus, Sarah's age is 10 years and Antonio's age is 2 years.
#1 is 11.2
2 is 6/50
3 is 1, 2, 3, 4, 6, 8, 12, 24
4 is 0
5 is 7
6 is 6
7 is 5 cm
8 is 16
9 is 48
10 is 0.023
Move the negative sign to the left
-x/5 = -20
Multiply both sides by 5
-x = -20 × 5
Simplify 20 × 5 to 100
-x = -100
Multiply both sides by -1
<em>x = 100</em>
<u>C. 100</u>
