Answer:
13 and 53
Step-by-step explanation:
First Integer: x
Larger integer: 5x-12
66=x+(5x-12)
66= x+5x-12
66=6x+12
78=6x
13=x
First Integer: 13
Larger Integer: 13*5-12= 65-12=53
Check Work:
13+53=66
Answer:
FG=13
Step-by-step explanation:
We can make an equation that looks like this:
EF+FG=EG
Then, we can substitute in the numbers we know:
12+FG=25
Then solve:
FG=25-12
FG=13

Answer:
Width of the rectangle = 5 inches
Length of the rectangle = 20 inches
Step-by-step explanation:
Let us assume the width of the rectangle = m in
So, the length of the rectangle = 4 (Width) = (4 m) in
Perimeter of the rectangle = 50 inches
Now, Perimeter of the Rectangle = 2 (LENGTH + WIDTH)
⇒ 2( m + 4m) = 50
or, 2(5m) = 50
⇒ 10m = 50 or, m = 50/10 = 5
⇒ m = 5
So, the width of the rectangle = 5 inches
and the length of the rectangle = 4 m = 4 x 5 = 20 inches
Answer:
There were 20 questions on the quiz
Step-by-step explanation:
In this question, we are concerned with knowing the number of questions on a quiz, given that Deana had a certain percentage after scoring an amount of marks.
We proceed as follows;
Let the number of questions on the quiz be X.
Now, she got 85% by making 3 incorrect choices. This means the percentage of questions she got incorrectly would be 100-85 = 15%
what we are saying is that it is just 15% of her questions that were wrong.
This mathematically;
15% of x = 3
15/100 * x = 3
15x = 3 * 100
15x = 300
x = 300/15
x = 20
area = l x w
area = 9 x 9
area = 81
Hope this was helpful. :-)
