Answer:

6

Step-by-step explanation:

75−3.5y−4y=4y+6

Step 1: Simplify both sides of the equation.

75−3.5y−4y=4y+6

75+−3.5y+−4y=4y+6

(−3.5y+−4y)+(75)=4y+6(Combine Like Terms)

−7.5y+75=4y+6

−7.5y+75=4y+6

Step 2: Subtract 4y from both sides.

−7.5y+75−4y=4y+6−4y

−11.5y+75=6

Step 3: Subtract 75 from both sides.

−11.5y+75−75=6−75

−11.5y=−69

Step 4: Divide both sides by -11.5.

−11.5y

−11.5

=

−69

−11.5

y=6

Hope this helps!

Answer: 6

Step-by-step explanation:

75 - 3.5y - 4y = 4y + 6

We solve by collecting like terms i.e.

75 - 6 = 4y + 4y + 3.5y

69 = 11.5y

y = 69/11.5

y = 6

Ludmilka [50]
No, because the sum of the total angle measure (or whatever it is called) is 720°, but those numbers only add up to 710°

What value(s) of x will make each equation below true? <br><br> 2x – 6 = 3x +1-x-7
puteri [66]

The answer is any value that you put in for x would make the equation true. When you simplify the whole equation it looks like this: 2x - 6 = 2x - 6, therefor you could replace x with any value.

Data collected from Cape Town shows that
Mademuasel [1]

Answer:

4%

Step-by-step explanation:

We know that 60% of drivers are over 30 years old and 5% of the 60% will be prosecuted for driving offence during the year. We know that 40% are 30 years and younger and 10% of that 40% will be prosecuted. The possibility of a driver 30 and younger being prosectued is:

=0.4\cdot{0.1}=0.04

Therefore the probability is 4%

What is the value of x and y
leva [86]

Answer:

x = +2√21 and y = +2√30

Step-by-step explanation:

The two marked sides of the smaller triangle are x and y.  The third side has length equal to 14 - 8, or 6.

We can thus write two equations in x and y:

x^2 = y^2 + 6^2

and

y     6

-- = ---

8     y

Solving the first equation for y^2 yields y^2 = 36 - x^2.  Solving the second equation for y^2 yields 48.  Thus 36 - x^2 = 48, and

x^2 = 84.  Thus, x = +√7*√4*√3, or x = +2√21.

We now find y.  y^2 = 36 = x^2, which here becomes

y^2 = 36 + 4(21) = 36 + 84 = 120.  Thus, y = +√4*√30, or y = +2√30.

Alecsey [184]

Answer:mean

Step-by-step explanation:

I would assume it’s the mean since that averages the 7 test scores it represents the data set well. Outlier and mode don’t describe a data set since they are quite unique within it.
