Solve the system of equations by substitution.
3/8x + 1/3y = 17/24
x + 7y = 8

Answers

Using the second equation, let’s find x

x + 7y = 8
x = 8 - 7y

Substitute x in the other equation

3/8(8 - 7y) + 1/3y = 17/24
3 - 21/8y + 1/3y = 17/24
-55/24y = -55/24
y = 1

Plug in y in any equation

x + 7(1) = 8
x + 7 = 8
x = 1

x = 1 and y = 1

WILL GIVE BRAINLIEST TO WHOEVER ANSWERS FIRST AND GETS IT RIGHT!!!

Answers

Hello there!

Grace has $105 for pizzas and a cake.

She sets aside $25, so we subtract:

105-25=80

So she has $80 for pizzas.

Now, to find out how many pizzas Grace can buy, we take $80 and divide it by the price of one pizza (9.25):

The approximate answer is 8.6

3

Answers

Step-by-step explanation:

T | 0 | 1 | 2 | 3 |

C | 24 | 21 | 18 | 15 |

Rule:

To find a rule, we need to find 2 things- what T is multiplied by and what is added.

To find what it is multiplied, we need to see the increase or decrease in C for every T. In this equation, there is a decrease of 3, so we multiply T by -3.

To find what is added, we go to 0 T and find the corresponding number. When T is 0, C is 24 so we add 24.

We write a rule as: y = mx + c, or in this case, c = mt + a

So the rule is c = -3x + 24

Jordan and Ben exercise at the same gym. The table below shows the number of calories they burned in each of their last 5 workouts.
How many calories would ben need to burn in his next workout to have the same average as Jordan?

Answers

Answer: The answer is 55 more calories than jordan in the next session

Step-by-step explanation: So sorry, I am bad at explaining :(

Answer:

760 calories

Step-by-step explanation:

Jordan's average is ...

(850 +674 +729 +658 +614)/5 = 705

Then the total number of calories Ben needs to burn in 6 sessions is ...

705×6 = 4230

So far, Ben has burned ...

716 +635 +802 +687 +630 = 3470 . . . calories

So, in his next session, Ben must burn ...

4230 -3470 = 760 . . . calories

To have the same average after 6 sessions that Jordan now has after 5 sessions, Ben must burn 760 calories in his 6th session.

Find the 8th term of the geometric sequence whose common ratio is 3/2 and whose first term is 3

Answers

Step-by-step explanation:

relax ! don't panic. just breathe deeply and then focus again.

a geometric sequence means that every new term is created by multiplying the previous term by a constant factor.

this factor is given here as 3/2.

this is called common ratio, because of that building rule the ratio of 2 consecutive terms is

an/an-1 = factor = 3/2

the first term is 3.

so,

a1 = 3

a2 = a1×3/2 = 3×3/2 = 9/2

a3 = a2×3/2 = a1×3/2 × 3/2 = 3× 3/2 × 3/2 = 27/4

we see

an = an-1 × 3/2 = a1 × (3/2)^(n-1) = 3 × (3/2)^(n-1)

and therefore

a8 = 3 × (3/2)⁷ = 3× 2187/128 = 6561/128 = 51.2578125
