Answer:
No solution
Step-by-step explanation:
Substitution method:
(Since y values are defined, make them equal to each other)
y = 152 + 9
y= 22 – 20
152 + 9 = 22 -20
161 ≠ 2
A false statement
Answer:
21.4m
Step-by-step explanation:
Circumference : x diameter
is approximately 3.142
3.142 x 6.8 = 21.3656
Nearest tenth = 21.4m
Your answer in the sum is 0.26
Hopes this helps:
Answer: x = -10/7
1. Simplify 2 • 2 to 4
4 + 7x + 6 = 0
2. Simplify 4 + 7x + 6 to 7x + 10.
7x + 10 = 0
3. Subtract 10 from both sides.
7x = -10
4. Divide both sides by 7.
X = -10/7
It is a very simple answer but it works!
