Answer:
<h3> A: One</h3><h3> B: x = 4 </h3>
Step-by-step explanation:
3(2x - 7) = 3
÷3 ÷3
2x - 7 = 1
+7 +7
2x = 8
÷2 ÷2
x = 4
A) is 2.5 x 10^4
B) is 8.1 x 10^3
C) is 90.6 x 10^6
D) is 10.34 x 10^7
Sorry if I’m wrong, x
There is a formula for that;
Total time = (Worker 1 * Worker 2) / (Worker 1 + Worker 2)
Total time = (80 * 120) / (80 + 120)
Total time = 9,600 / 200
Total time = 48 minutes
1) 136 is the circumference of a circle with what area? we know C=πd.
136=πd
136/π=d
d=43.290 so the radius is half that, or
r=21.645
taking area as our measure of size,
A=πr²
A=π•21.645²
A=1471.855. answer C is closest. difference is in how they and I rounded
2) c, e, and f
