Answer:
A
Step-by-step explanation:
The equation 9(u – 2) + 1.5u = 8.25 models the total miles Michael traveled one afternoon while sledding, where u equals the number of hours walking up a hill and (u – 2) equals the number of hours sledding down the hill. Which is the value of u?
u = 0.25
u = 0.75
u = 1.1
u = 2.5
Answer:
D: U= 2.5
Step-by-step explanation:
The value of u in the equation is approximately 2.5
Algebraic equation 9(u – 2) + 1.5u = 8.25
where
(u – 2) = the number of hours sledding down the hill
The value of u can be found as follows:
9(u – 2) + 1.5u = 8.25
9u - 18 + 1.5u = 8.25
combine like terms
9u + 1.5u - 18 = 8.28
add 18 to both sides
10.5u = 8.28 + 18
10.5u = 26.28
divide both sides by 10.5
u = 26.28 / 10.5
u = 2.50285714286
u = 2.5

Write the first ten terms of a sequence whose first term is -10 and whose common difference is -2.
Write the first ten terms of a sequence whose first term is -10 and whose common difference is -2.
Solution:[tex] - 10 - ( - 2) = \boxed{ - 8}[/tex]
[tex] - 8 - ( - 2) = \boxed{ - 6}[/tex]
[tex] - 6 - ( - 2) = \boxed{ - 4}[/tex]

A circle has a radius of 4 feet. What is the radius of a bigger circle if the scale factor of the smaller to bigger is 4:9
Answer:
9 feets
Step-by-step explanation:
From the question, we have our scale factor as:
4:9 = 4/9
Smaller circle /Bigger circle = 4/9
A circle has a radius of 4 feet. What is the radius of a bigger circle?
Let the radius of the bigger circle = x
This is calculated as:
4/9 = 4/x
Cross Multiply
4x = 9 × 4
x = 36/4
x = 9 feet
Therefore, the radius of the bigger circle is 9 feet

Solve the following equation:
2(3x + 10) - 8x = 52
Answer: x=−16
Step-by-step explanation: 2(3x+10)−8x=52

help please how do i do this
Answer:
m<A = 39
Step-by-step explanation:
1. Approach
To solve this problem, one first has to find the value of "x", then one will substitute "x" back into the equation given for the value of m<A, to solve for m<A. In order to solve this problem, one has to know that the sum of angle measures in a triangle will always equal 180.
2. Solving for "x"
The sum of angle measure in a triangle will always equal 180 degrees, hence one can set up an equation,
m<A + m<B + m<C = 180
Substitute,
(10x - 1) + (18x + 2) + (15x + 7) = 180
Simplify,
43x + 8 = 180
Inverse operations,
43x + 8 = 180
-8 -8
43x = 172
/43 /43
x = 4
3. Solve for m<A
Now all one has to do is substitute the value of "x" back in to solve for m<A
10x - 1
x = 4
10(4) - 1
40 - 1

Triangle ABC is similar to triangle DEF. Solve for r.
Answer:
9
Step-by-step explanation:
since they're similair then similair sides will be proportional
CB is similair to EF
[tex]\frac{6}{8}[/tex]= [tex]\frac{3}{4}[/tex]
same thing if you try with the hypotenuse AB similair to DE
[tex]\frac{13.5}{18}[/tex]= [tex]\frac{3}{4}[/tex]
So, if you multiply r (DF) by 3/4 you will get the similair side AC
rx 3/4=12
r= 12÷ 3/4
r=16

16/15
[tex]1 \frac{1}{15} [/tex]
20/17
[tex]1 \frac{3}{17} [/tex]
Answer:
Step-by-step explanation:
1. When changing from improper fractions to mixed fractions, you have to divide the denomenator by the numerator and that is 7÷6 which should give you 1 remainder 1. Therefore ypur mixed fraction is 1 whole number 1/6.
2. 20/17 = 20 dividing 17 (20÷17)
Which is 1 whole number 3/17
3. Now the third too is 16/15 which is 16 dividing 15 (16÷15).
Therefore your answer is 1 whole number 1/15.
But in order to be sure of your answers, you will have to multiple the denomenator by the whole number plus the numerator.
