Can someone help me<br> 7 + 2h = 3 + 4h
STALIN [3.7K]

h = 2

7 + 2h = 3 + 4h

You must isolate the variable to solve using the order of operations, or PEMDAS.

4 = 2h

Subtract 3 from both sides of the equation, and subtract 2h from both sides of the equation.

\frac{4}{2}  = h

Divide both sides of the equation by 2.

h = 2

sergeinik [125]
The answer is 28.

1/4 of 16= 4
3/4 of 16= 12
so Carmen takes 3/4 more time of the trip to the market when she return s home.

Find the value of x (4x-9) (3x+29)
polet [3.4K]

Answer:

12x³+89x²-261x (?)

Step-by-step explanation:

For this equation, I am going to assume you want to find the value of the expression and you're multiplying all the values (since you can't find the value of x with this unless you had an equation).

(x)(4x-9)(3x+29)

(4x²-9x)(3x+29)

12x³+89x²-261x

X would be 84 degrees, since its corresponding angle would be worth 84.
Hope this helped!

Simple question just answer correctly to get brainleist and 10 pts! :)
Natali [406]

Answer:

d.  The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.

Step-by-step explanation:

This would be a function as long as one x-value doesn't correspond to two y-values. If two x-values correspond to one y-value though, it still represents a function.
