Think about the individual parts of the expression.
5b - a
5b equals 625. Therefore, 5b - a = 625 - a
Now you have 625 - a.
If 5a = 25, then what does "a" equal? Divide 5 from both sides to find out.
5a/5 = 25/5
a = 5
Therefore, 625 - a = 625 - 5
625 - 5 = 620
620 is the answer.
When you add, you subtract the exponents. When you divide, you subtract the exponents.
When you have multiplication and division in one expression, you do it from left to right.
7^2 times 7^5 = 7^ (2+5) = 7^7
7^7 times 2^2 / 7^3 = 7 ^(7 - 3) times 2^2
7^4 times 2^2 times 2^6 = 7^4 times 2^(2+6) = 7^4 times 2^8
Put it in a calculator.
614656.
That is the answer, but you didn't include the "which of the following", so I guess you'll have to put each value in the calculator to find out!
If the 7^3 times 2^6 is in parenthesis, then the answer is 150.0625.
Answer: 44.5 ft²
Step-by-step explanation:
The area of pink blanket is considering A=5\times 5.7=28.5 and the area of a rectangle is A=l\times w
.
Now we have area of the pink blanket which is 28.5.
The area of blue blanket - A=24=6 x 4
Area of a triangle: A= 1/2 x base x height and that is 1/2 x 4 x 4 which is 8. and that is the area of both blankets.
Now, pink blanket 28.5 x blue blanket 24 minus 8 is giving us the number that is referring to total area that is covered and that is 44.5 ft²
Answer:
Given : s||t
Exterior sides in opposite rays : ∠5 and ∠7 are supplementary
Definition of supplementary angles : m∠5 + m∠7 = 180°
If lines are ||, corresponding angles are equal : m∠1 = m∠5
Substitution : m∠1 + m∠7 = 180°
Answer:
Step-by-step explanation:
x+x+11+x+9=32
3x+20=32
-20 from each side
3x=12
divide by 3
x=4.
11+4=15
9+4=13
