b + 2 = -18 find what the letter b means
Answer:
b = -20
Step-by-step explanation:
b + 2 = -18
b = -20
Answer:
b= -20
Step-by-step explanation:
the first step is to subtract 2 from both sides of the equation.
b + 2 = -18
-2 -2
-------------------
the -2 and +2 cancel
b = -20

BIU.
as an exponential expression with a single base and exponent
Answer:
a-n=1
Step-by-step explanation:
Write the equation of the line in fully simplified slope/intercept form
Answer:
y = m x + b standard form for straight line
m = (y2 - y1) / (x2 - x1)
When y2 = 12, x = -6
when y = 0, x = -2
m = (12 - 0) / (-6 - (-2)) = -3
so y = -3 x + b
Also, when x = 0, y = -6
Our equation is
y = -3 x - 6
As a check try x = -2
y = (-3 * -2) + (-6) = 0 as the graph shows
can anyone help me with this problem with a full explanation?? thank you
Answer:
15, 16, 17
Step-by-step explanation:
let the consecutive numbers be n , n + 1 , n+ 2 , then
n + n + 2 = 32 ( sum of first and third )
2n + 2 = 32 ( subtract 2 from both sides )
2n = 30 ( divide both sides by 2 )
n = 15
n + 1 = 15 + 1 = 16
n + 2 = 15 + 2 = 17
The 3 numbers are 15, 16, 17
Step-by-step explanation:
let the 1st and 2nd consecutive number be
x , x + 1 , x + 2
their sum = 32
so, x + x + 2 = 32
→ 2x + 2 = 32
→ 2x = 32 - 2 = 30
→ x = 30/2 = 15
so,
1st and 3rd consecutive number is
x = 15
x + 2 = 15 + 2 = 17
as they are consecutive number so 2nd number is 16
and a/q sum of 1st and 3rd number is 32
15 + 17 = 32
hope this answer helps you dear...take care and may u have a great day ahead!
Help me please!!! It’s due at 11:59
Answer:
18
Step-by-step explanation:
Let the required number be x.
Step 1write the expression for the difference of the number and 4.
=> x - 4
Step 2the question equates 5 times the difference with some other terms, so find the equation for 5 times the difference.
=> 5( x - 4)
Step 3The equation in Step 2 is said to be equal to "two less than four times the number".
Find the expression for four times the number
=> 4x
Step 4Find the expression for two less than 4x.
=> 4x - 2
Step 5Equate the terms that it says are equal:
=> 5(x - 4) = 4x - 2
distributing 5 within the parenthesis:
=> 5x - 20 = 4x - 2
taking like terms on one side:
=> 5x - 4x = 20 - 2
(the sign carried by the terms get inverted while changing their sides)=> x = 18
and x was the required number, so the answer Is 18.

8n - 7 = -5(-3n - 7)
Solve Multi-Step equation.
Please explain how you i can understand too!
Answer:
n=-6
Step-by-step explanation:
8n-7=-5(-3n-7)
Multiply -5 to -3n and -7
8n-7= 15n+35
Bring 8n to the other side by subracting it from 15n
-7=7n+35
Subtract 35 from both sides
-42=7n
Divide both sides by 7
n=-6
A class contributed $19.00 in quarters and dimes to a local homeless shelter. In
all there were 100 coins. How many were there of each kind.
Answer: 60 quarters and 40 dimes
Step-by-step explanation:
Step 1: Setup Coin Value and Coin Total Equation:
Coin Value Equation → 0.1d + 0.25q = $19.00 where d = dimes and q = quarters
Coin Total Equation → d + q = 100
Step 2: Rearrange Coin Total Equation in terms of dimes (d)
d = 100 - q ← Revised Coin Total Equation
Step 3: Plug in our Revised Coin Total Equation for d into our Coin Value Equation:
0.1(100 - q) + 0.25q = $19.00
0.1(100) - 0.1(q) + 0.25q = $19.00
10 - 0.1q + 0.25q = $19.00
10 + (0.25 - 0.1)q = $19.00
10 + 0.15q = $19.00
Step 4: Subtract 10 from each side of the equation to isolate q
10 - 10 + 0.15q = $19.00 - 10
0.15q = 9
Step 5: Divide each side of the equation by 0.15 to isolate q
0.15q/0.15 = 9/0.15
q = 60
Step 6: Using our value for q, Solve for d using our Coin Total Equation:
d + 60 = 100
Subtracting 60 from both sides, we get d + 60 - 60 = 100 - 60
d = 40
Summarizing our word problem, we see that 60 quarters and 40 dimes add up to $19.00
