find the value for m
-10 + 59 = 5m = 7 + 3m
-10+59=5m=7+3m
49=5m=7+3m
49-7=5m-3m
m=42/2
m=21
Answer:
21
Step-by-step explanation:
-10+59 = 5m = 7 + 3m
49 = 5m = 7 + 3m
49 - 7 = 5m - 3m
42 = 2m
42/2 = m
m= 21

. For what value of x do the expressions 2x +2 and 3x – 6 have the same value?
Answer:
x = 8
Step-by-step explanation:
To find the solution, equate the 2 expressions, that is
3x - 6 = 2x + 2 ( subtract 2x from both sides )
x - 6 = 2 ( add 6 to both sides )
x = 8
As a check
2x + 2 = 2(8) + 2 = 16 + 2 = 18
3x - 6 = 3(8) - 6 = 24 - 6 = 18
Both expressions have the same value when x = 8
How many different 4-digit PIN codes are there that only include the digits 4, 5, 6, 7, 8 and 9
if each of those digits is only allowed to be used once?
Answer:
ecall that 6 + 6 + 6 = 6 × 3
Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.
Similarly,
6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42
Still by the same token,
2 + 2 + 2 + 2 = 2 × 4
In algebra, 2 × 4 can be written as (2)(4)
You can think of this as four groups of 2.
This situation is shown in the number line below.
You basically start at 0 and count by 2's until you have put four 2's on the number line. You end up at 8 and 8 is positive.

A beachball has a radius of 10 inches. Find the volume of the beachball, in cubic inches.
Round your answer to the nearest whole number.
Answer:
4189 cubic inches
Step-by-step explanation:
Use the formula for the volume of a sphere: V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³
Plug in the radius as r, and simplify:
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](10³)
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](1000)
V = 4188.79
Round to the nearest whole number
= 4189
So, the volume of the beachball is 4189 cubic inches
Melody Pond and a tree cast a shadow at the same time of day. Melody is 5.6 feet tall and casts a 10-foot shadow. If the length of the tree's shadow is 62 feet, what is the height of the tree?
Answer:
34.72 feets
Step-by-step explanation:
Using the relation :
Length of tree / shadow of tree = height of melody / shadow of melody
From the details given in the question :
Let height of tree = h
h / 62 = 5.6 / 10
Cross multiply
h * 10 = 62 * 5.6
h = 347.2 / 10
h = 34.72 feets
Hence, the height of tree is 34.72 feets

I WILL GIVE OUT BRAINELIST Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the graph of h(x) is 12 units above the vertex of the graph of g(x) .
Which pair of functions could have been used to create the graphs of g(x) and h(x)?
h(x)=(x+12)2 and g(x)=x2
h(x)=x2−12 and g(x)=x2
h(x)=x2+12 and g(x)=x2
h(x)=(x−12)2 and g(x)=x2
Answer:
h(x)=(x-12)2 and g(x)=2
Heather Johnson bought a new set of tires for $436.00 and a car seat for $22.85. The state tax rate is 6%, the county tax rate is 1.5%, and the city tax rate is 0.5%. What is the total purchase price?
Answer:
$495.56
Step-by-step explanation:
Tax increases the price paid for a good or service. So, the total price paid for the goods would increase by the total amount of tax
Sum of the three taxes = 6% + 1.5% + 0.5% = 8%
Total cost of items purchased = $436 + $22.85 = $485.85
Total purchase price = Total cost of items purchased x (1 + total tax)
$485.85 x (1.08) = $495.56
If 3 x/4 +2 =56.8, what is the value of x?
A) x≈ −2.891
B) x≈ 6.708
C) x≈ −4.323
D) x≈ −2.059
Answer:
the value of the x is 73.07
Step-by-step explanation:
The computation of the value of the x is shown below:
Given that
3x ÷ 4 + 2 = 56.8
3x + 8 ÷ 4 = 56.8
3x + 8 = 56.8 × 4
3x + 8 = 227.2
3x = 227.2 - 8
3x = 219.2
x = 73.07
Hence, the value of the x is 73.07

The equation h = -16t 2+ 53x + 8 gives the height h, in feet, of a football as a function of time t, in seconds, after it is kicked. What is the maximum height the football reaches?
Answer: The maximum height the football reaches = 51.89 feet.
Step-by-step explanation:
Given: The equation [tex]h = -16t^2+ 53t + 8[/tex] gives the height h, in feet, of a football as a function of time t, in seconds, after it is kicked.
Differentiate the given equation, we get
[tex]h'=-(2)16t+53=-32t+53[/tex] (i)
Put [tex]h'=0[/tex]
[tex]\Rightarrow\ -32t+53=0\\\\\Rightarrow\ t=\dfrac{53}{32}\approx1.65625[/tex]
Differentiate (i) w.r.t. t, we get
[tex]h''=-32[/tex] < 0 i.e. h is maximum at t= 1.65625
The value of h at t= 1.65625 will be [tex]-16(1.65625)^2+53(1.65625)+8=51.890625\approx51.89\text{ feet}[/tex]
Hence, the maximum height the football reaches = 51.89 feet.
