Algebra I

Step-by-step explanation:

Step 1: Define

Identify

3x + 5(2 + x) = 4x - 7

Step 2: Solve for x

Answer:

x=[tex]\frac{-17}{4}[/tex]

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x+5(2+x)=4x−7

3x+(5)(2)+(5)(x)=4x+−7(Distribute)

3x+10+5x=4x+−7

(3x+5x)+(10)=4x−7(Combine Like Terms)

8x+10=4x−7

8x+10=4x−7

Step 2: Subtract 4x from both sides.

8x+10−4x=4x−7−4x

4x+10=−7

Step 3: Subtract 10 from both sides.

4x+10−10=−7−10

4x=−17

Step 4: Divide both sides by 4.

[tex]\frac{4x}{4}[/tex]=[tex]\frac{-17}{4}[/tex]

x=[tex]\frac{-17}{4}[/tex]

Answer: 60 days

Step-by-step explanation:

To get the number of days that both of them will be washing the cars on thesame day, we have to find the lowest common multiple of 15 and 20. This will be:

Multiple of 15 = 15, 30, 45, 60, 75, 90

Multiples of 20 = 20, 40, 60, 80, 100

Lowest common multiple = 60

Therefore, they'll be Washing the car on thesame day on the 60th day.

Answer:

m = -24

Step-by-step explanation:

(m/6) - 7 = -11

Add 7 to each side

(m/6) - 7+7 = -11+7

m/6 = -4

Multiply each side by 6

m/6 *6 = -4*6

m = -24

Answer:

Step-by-step explanation:

m/6-7=-11

m-6*7/6=-11

m-42=-11*6

m-42=-66

m=-66+42

m=-24

Answer:

166.5 cm squared

Step-by-step explanation:

Multiply 11x11 =121

Multiply 7x6.5 =45.5 (we get the 7 because 18-11=7)

Then we add 121 and 45.5 and get 166.5

The area of this composite shape is 166.5 square cm

Composite figures are figures that has more than 1 shape. The given figure is made up of two rectangles.

The area of the shape is given as shown below;

Area = (11*11) + (7 * 6.5)
Area = 121 + 45.5

Area = 166.5 square cm

Hence the area of this composite shape is 166.5 square cm

What is the measurement?

Measurement is the process of finding a number that shows the amount of something. Time the ongoing sequence of events is time. We can measure time in seconds, minutes, hours, days, weeks, months, and years.

Here given that,

The club will base its decision about whether to increase the budget for the indoor rock climbing facility on

the analysis of its usage. The decision to increase the budget will depend on whether members are using

the indoor facility at least two times a week. Use the best measure of center for both of the original data

sets to determine whether the club should increase the budget.

As per this we get that,

Yes, they can increase the budget, because both Manuel has [tex]8[/tex] and Gretchen [tex]9[/tex] are at least [tex]8[/tex] and [tex]8[/tex] times per month is equivalent to the two times per week.
