0.50x+0.15(30)=23.5
Multiply 0.15 and 30 to get 4.5.
0.5x+4.5=23.5
Subtract 4.5 from both sides.
0.5x=23.5−4.5
Subtract 4.5 from 23.5 to get 19.
0.5x=19
Divide both sides by 0.5.
[tex]x=\frac{19}{0.5}[/tex]
Expand [tex]\frac{19}{0.5}[/tex] by multiplying both numerator and the denominator by 10.
[tex]x=\frac{190}{5}[/tex]
Divide 190 by 5 to get 38.
x=38

Do I minus by 10 on each side or do I add minus by 7?
Answer:
[tex] \sf \large{m=−3}[/tex]
Step-by-step explanation:
Let's solve your equation step-by-step.
10=7−m
Step 1: Simplify both sides of the equation.
10=7−m
10=7+−m
10=−m+7
Step 2: Flip the equation.
−m+7=10
Step 3: Subtract 7 from both sides.
−m+7−7=10−7
−m=3
Step 4: Divide both sides by -1.
−m/−1= 3/−1
m=−3
given g(x) is ...............
Answer:
-40
Step-by-step explanation:
It states with g(-2) that x = -2, so we can plug -2 for x.
g(x) = 3x^3 - 2x^2 + 4x
g(x) = 3(-2)^3 - 2(-2)^2 + 4(-2)
g(x) = 3(-8) - 2(4) + 4(-2)
g(x) = -24 - 8 - 8
g(x) = -40

The correct solution of division fractions is 18/4.
What is division?Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. The primary objective of division is to count the number of equal groups that are created or the number of individuals in each group after a fair distribution.
When describing how much of anything is left over, a fraction is used. It represents the appropriate parts of the totality. A fraction is made up of two parts: the numerator and the denominator

The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 500 minutes, the monthly cost will be $132. If the customer uses 700 minutes, the monthly cost will be $172.
A) Find an equation in the form
y=mx+b
where
x
is the number of monthly minutes used and
y
is the total monthly of the Ringular plan.
The equation in the form y = mx + b is as follows:
y = 1 / 5 x + 32
How to represent a linear equation?The customer uses 500 minutes, the monthly cost will be $132. If the customer uses 700 minutes, the monthly cost will be $172.
Using linear equation in slope intercept form,
y = mx + b
where
m = slopeb = y-interceptHence,
x = the number of monthly minutes used
y = the total monthly of the Ringular plan
Therefore, the equation in slope intercept form can be represented as follows:
(500, 132)(700, 172)
let's find the slope,
m = 172 - 132 / 700 - 500
m = 40 / 200
m = 4 / 20
m = 1 / 5
Hence,
y = 1 / 5x + b
using (500, 132) let's find the y-intercept
132 = 1 / 5 (500) + b
132 = 100 + b
b = 132 - 100
b = 32
Therefore, the equation in the form y = mx + b is as follows:
y = 1 / 5 x + 32

A 500 kg car heads through a loop with a 20 m radius. At the top of the loop, the car is moving at 14 m/s. If air resistance is negligible, what would the car's velocity be at the bottom of the loop?
The speed of the car at the bottom of the loop is approximately 31.3 m/s
How can the velocity at the bottom of the loop be calculated?The given parameters are;
Mass of the car = 500 kg
Radius of the loop = 20 meters
Velocity of the car at the top of the loop = 14 m/s
The kinetic energy at the top of the loop is therefore;
K E. = 0.5×500×14² = 49,000
The potential energy gained = 500×9.81×40 = 196200
Total energy = 49,000 + 196,200 = 245,200
The velocity at the bottom is therefore;
0.5×500×v² = 245,200
v² = 245,200 ÷ (0.5×500) = 980.8
v = √(980.8) ≈ 31.3
The velocity at the bottom of the loop is therefore;
v ≈ 31.3 m/sLearn more about the conservation of energy principle here:
