Answer:
A. 0.25q + 0.10d = 1.00
q + d =7
Step-by-step explanation: Only logical choice I see. The others mix up values and units.
The system of equations is
0.25q + 0.10d = 1.00
q + d =7
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
A jar contains "q" quarters and "d" dimes.
There are 7 coins in the jar and the total value of the coins is $1.00.
As, 2 quarters and 5 dimes
= 2(.25) + 5(.10)
= $.50+ $.50
= $1
Now, according to question,
0.25q + 0.10d = 1
and, 0.10q + 0.10d = 0.7
Solving above equation we get
0.15q = 0.3
q = 2 quarter
Then, d= 7 -q = 7- 2 = 5 quarter

What operation do we use to solve unit rate?
FAST PLEASE
Answer:
Step-by-step explanation:
Calculator Use
A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.

Please answer correctly !!!! Will mark Brianliest !!!!!!!!!!!
Step-by-step explanation:
since they are in order points p and q are in the middle and points O and R are on the end so they say that OR=36 since you don't know the exact lengths of all of the lengths in the middle from O to R then you multiply 5,6 and 1 by x and add
5x+6x+1x=12x
so then the whole length is equal to the ratio of 12x and also 36 so set those to equal each other
12x=36
x=3
so that is just the ratio and since they are asking for the length of O to Q that means that it is just 5x+6x=OQ
11x=OQ
insert x=3
33=OQ
Hope that helps :)

If the simple interest on $7,000 for 2 years is 980, then what is the interest rate?
Answer:
7%
Step-by-step explanation:
since the formula says si=ptr/100
so we have to separate r which gives us r =(i ×100)/(p×t)
now putting the values (980×100)/(7000×2)
=7
therefore the rate of interest is 7%

At Penny's Pie Shop, it costs $4 for
1
4
of a pie. What is the cost of a whole pie?
Simplify your answer and write it as a proper fraction, mixed number, or whole number.
Answer:
$16
Step-by-step explanation:
$4 for 1/4 of a pie, means that it isn't an entire pie. Luckily for us, this is simple multiplication. You would multiply like so:
4 x 4 = 16
And you'd get your answer, since 4/4 equals 1 whole.
I hope I helped you, and a "Brainliest" is always appreciated! ☺
