Answer:20x+50= 5x+70
Step-by-step explanation:
x = number of cavities
use the subtraction property of equality and solve for x
20x+50 = 5x+70
-5x -50 -5x - 50
15x = 20
Then you divide 20 by 15
15x = 20

x= 4/3
Answer:
false
Step-by-step explanation:
The correct answer is: Option (D) x = 72°
Explanation:
When two lines are crossed by another line, the angles in matching corners are called <em>corresponding angles</em>. When the two lines are <em>parallel</em>, the corresponding angles are <em>equal</em>.
Here in this case, the two lines are "AB" and "CD", and both are parallel and are crossed by the line; therefore, <em>the corresponding angles will be the same</em>.
Since the first corresponding angle is 72°, the second angle <em>x </em>will be 72° as well. The correct answer is: x = 72° Option (D).
Answer:
There are 8 penguins and 6 reindeers.
Step-by-step explanation:
Since Brian, the gorilla, was planning a party for his zoo friends, and he sent his elves Jamie and Nancy into the North Pole exhibit to count the penguins and reindeer, and Jamie said there were 40 legs and Nancy said there were 14 heads To determine how many penguins and reindeer were in the exhibit, the following calculation must be performed:
Penguins: 1 head and 2 legs
Reindeers: 1 head and 4 legs
40 - (14 x 2) = X
40 - 28 = X
12 = X
12/2 = 6
14 - 6 = 8
8 x 2 + 6 x 4 = X
16 + 24 = X
40 = X
Therefore, there are 8 penguins and 6 reindeers.
Answer: 3.6 cups or 3 3/5 cups
Step-by-step explanation: what i would do here is set up a proportion. Change 3/4c to .75 cups as it’s easier to place in a proportion (and less confusing).. cross multiply .... (.75 x 48= 36) then divide 36 by 10 and that will give you x
