(25-a) divided by 7=3
Answers
Answer:
a = -0.57
rounded to the nearest tenth: a = -0.6
Step-by-step explanation:
(25 - a) ÷ 7 = 3
25 - a ÷ 7 = 3
25 ÷ 7 - a = 3
3.6 - a = 3
3.57 - 3.57 - a = 3 - 3.57
a = -0.57
The value of "a" in the equation (25 - a) ÷ 7 = 3 is 4.
To find the value of "a" in the equation (25 - a) ÷ 7 = 3.
we can solve for "a" by isolating it on one side of the equation.
(25 - a)/7 = 3.
Multiply both sides of the equation by 7 to get rid of the division:
7(25 - a)/7 = 3 × 7.
25 - a = 21.
To isolate "a," subtract 25 from both sides of the equation:
25 - a - 25 = 21 - 25.
Simplifying further, we get:
-a = -4.
Multiply both sides of the equation by -1 to solve for "a":
-1 × (-a) = -1× (-4).
a = 4.
Therefore, the value of "a" in the equation (25 - a) ÷ 7 = 3 is 4.

Brad has a garden with dimensions 12 feet long x 7 feet wide. He wants to enlarge the garden to an area of 119 square feet. How much farther will he need to extend the length of the garden to attain his desired
Answers
Answer:
the length will need to be increased by 5 feet
He will need to 5 feet extend the length of the garden to attain his desired.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Brad has a garden with dimensions 12 feet long x 7 feet wide.
And, He wants to enlarge the garden to an area of 119 square feet.
Now,
Let the number of additional feet added to the length = x
So, We can formulate;
⇒ 7 (12 + x) = 119
⇒ 84 + 7x = 119
⇒ 7x = 119 - 84
⇒ 7x = 35
⇒ x = 5
Thus, He will need to 5 feet extend the length of the garden to attain his desired.
