Louis has three more quaters than dimes in his pocket, for a total of $1.80 . Which equation could used to detemine the number o

antoniya [11.8K]

Answer:

3+d=q and 0.10d+0.25q=1.80

There are 3 dimes and 6 quarters.

Step-by-step explanation:

This situation has two unknowns - the total number of dimes and the total number of quarters. Because we have two unknowns, we will write a system of equations with two equations using the two unknowns.

We know there are three more quarters than dimes. We write that as 3+d=q.

We also know the total cost and the value of each coin. We write 0.10d+0.25q=1.80.

We substitute 3+d for q in the second equation.

0.10d+0.25(3+d)=1.80

0.10d+0.75+0.25d=1.80

0.35d+0.75=1.80

We isolate the variable by subtracting 0.75 across the equal sign and then dividing by the coefficient of d.

0.35d=1.05

d=3

There are 3 dimes.

Rearrange to make subject x 4(x-3)/a=y

VikaD [51]

Answer:

answer is x = ay + 12/4

Step-by-step explanation:

first we cross multiply on both sides which will give us this

4( x -3)=ay

we then open the brackets by multiplying 4 with x and -3 which gives

4x - 12= ay

then take 12 to the other side

4x - 12+12= ay + 12

4x = ay + 12

divide 4 on both sides

4x /4= ay + 12/ 4

therefore x = ay + 12/ 4

Over 6 days, jim jogged 6.5,5,3,2,3.5, and 4 miles. What is the mean distance that Jim jogged

bonufazy [111]

To get the mean distance that Jim jogged, you have to solve for the total miles he was able to jogged divided by the number of days he jogged.

6.5 miles + 5 miles + 3 miles + 2 miles + 3.5 miles + 4 miles = 24 miles / 6 days = 4

Therefore, the mean distance that Jim jogged is 4 miles.

In the diagram of circle O, what is the measure of ? 27° 54° 108° 120°

vesna_86 [32]

Answer:

Option (2).

Step-by-step explanation:

This question is incomplete; here is the complete question and find the figure attached.

In the diagram of a circle O, what is the measure of ∠ABC?

27°

54°

108°

120°

m(minor arc $\widehat {AC}$ ) = 126°

m(major arc $\widehat {AC}$ ) = 234°

By the intersecting tangents theorem,

If the two tangents of a circle intersect each other outside the circle, measure of angle formed between them is half the difference of the measures of the intercepted arcs.

m∠ABC = $\frac{1}{2}[m(\text {major arc{AC})}-m(\text{minor arc} {AC})]$

= $\frac{1}{2}(234-126)$

= 54°

Therefore, Option (2) will be the answer.
