2a + b = 3 and a - 3b = 5
Answer:
a= 2 b=-1
Step-by-step explanation:
a-3b=5
or, a= 5+3b_(i)
substituting value of a in 2a+b=3,
2×(5+3b)+b=3
or, 10+6b+b=3
or, 7b=3-10
or, 7b=-7
b= -1
substituting value of b in(i),
a=5+3b
=5+3×(-1)
=5-3
=2

Combine like terms to create an equivalent expression.
3.4 - 2.8d +2.8d - 1.3
Answer:
2.1
Step-by-step explanation:
Simplifying
3.4 + -2.8d + 2.8d + -1.3 = 0
Reorder the terms:
3.4 + -1.3 + -2.8d + 2.8d = 0
Combine like terms: 3.4 + -1.3 = 2.1
2.1 + -2.8d + 2.8d = 0
Combine like terms: -2.8d + 2.8d = 0.0
2.1 + 0.0 = 0
2.1 = 0
Solving
2.1 = 0

On Dolores's tenth birthday her grandfather deposited $35 in a savings account for her. Each year, her grandfather deposited twice the amount of the previous year's deposit. How much money did her grandfather deposit on Dolores's eighteenth birthday?
Her grandfather deposits $28,680 on Dolores's eighteenth birthday.
What is a deposit?
A deposit is an amount of money that is placed into an account, typically a savings or checking account, with a financial institution such as a bank or credit union. The money deposited is held by the institution and can be withdrawn at a later time. Deposits can also refer to the act of putting money into an account.
In your example, on Dolores's tenth birthday her grandfather deposited $35 in a savings account for her. Each year, her grandfather deposited twice the amount of the previous year's deposit. On Dolores's eleventh birthday, the deposit was 352 = $70. The deposit for twelfth birthday was 702 = $140. Similarly, on Dolores's 18th birthday, the deposit was 35*2^8 = $28,680.
Hence, her grandfather deposits $28,680 on Dolores's eighteenth birthday.

A $500 loan for 2 years at an
interest rate of 15%
Answer:
Interest rate formula
I = PRT
where,
I = simple interest
P= principle
R= annual interest
T= relevant time period
I= PRT
I=500×15/100×2
I=150
total amount formula,
A=P+PRT
where,
A=total amount
A=P+PRT
A=500+150
A=650
answer,
interest amount=$150
total amount = $650

Rachel’s has a summer job working at the library. The graph below shows the relationship between the number of hours Rachael worked and the amount of money, in dollars, that Rachel earned?
Answer: m = 10 h
Step-by-step explanation: i did the test too
The Equation for Rachel Earning is m = 10h.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
From the graph we take two points (4, 35) and (5, 45).
So, the slope is
= (45 - 35) / (5-4)
= 10 /1
= 10
let Rachel work for h hours then Rachel earned
m = 10h

Solve 8x - 5y = 18 for y.
y=(Use integers or fractions for any numbers in the expression.)
Answer:
y=8/5x + 18/5
Step-by-step explanation:
subtract 8x on both sides which ends up looking like:
-5y = 18 -8x
divide -5 on both sides which ends up like:
y= 8/5x - 18/5
then u simplify, but there's not need for that because it's already simplified.
