Answer: 30
Step-by-step explanation:
Simple formula is
LCM*GCF=PRODUCT OF 2 NUMBERS
120 * 10 = 40 * x
1200 = 40x
x = 1200/40
x = 30
Answer:
The number of counties in state A are 70.
The number of counties in state B are 68.
Step-by-step explanation:
The number of counties in state A and the number of counties in state B are consecutive even integers whose sum is 138.
Let the two consecutive even integers be x and x+2.
As their sum is 138, we can denote this mathematically as :




Now, we get x = 68
And
= 70
Hence, the two numbers are 68 and 70.
So, the number of counties in state A are 70.
The number of counties in state B are 68.

Answer:
Center: (-7, -4)
radius = 4
Explanation:
- Equation: (x + 7)² + (y + 4)² = 16
Circle formula:
(h, k) denotes the center of the circle, "r is radius"
Rewrite the following equation in standard form:
- (x - (-7))² + (y - (-4))² = 4²
From this identify:
- h = -7, k = -4, radius = 4
