Answer:

1. Anne = 21 Bobby=35, 450, 70+40+30=140

Step-by-step explanation:

1 21÷3=7
7×5=35

7-2=250
5=250
1=50
2×50+7×50=100+350=450
450

we can see that it's multiplied by 10, so 70+40+30=140

Jason has 14 raspberry scones and 35 blackberry scones. He wants to make as many identical bags of scones as possible. Each bag

Natali5045456 [20]

Answer:

7 is the greatest number of bags Jason can fill.

Step-by-step explanation:

Given: Jason has 14 raspberry scones and 35 blackberry scones.

Now, finding the maximum number of bags Jason can fill with equal number of raspberry scones and blackberry scones.

∴ we will be using Greatest common factor (GCF) for knowing the number of bags.

$14 = 2\times 7\\\\35= 5\times 7$

∴ $GCF= 7$

7 is the greatest number of bags that Jason can fill with equal number of raspberry and blackberry scones.

An electrician charges a flat fee for each job plus an hourly rate . He charged one customer $90 for a job that took him 3 hours

lianna [129]

Answer:

let x equal the service charge.

let y equal the per hour charge.

for the job that cost 450, the equation is 450 = x + 6y

for the job that cost 330, the equation is 330 = x + 4y

these two equations needs to be solved simultaneously.

subtract the second equation from the firs to get 120 = 2y

solve for y to get y = 60.

in the first equation, replace y with 60 to get 450 = x + 6*60.

simplify to get 450 = x + 360.

subtract 360 from both sides of the equation to get 90 = x.

it appears that the service charge is equal to 90 and the per hour charge is equal to 60.

for the job that cost 450, the equation becomes 450 = 90 + 6*60 = 90 + 360 = 450.

for the job that cost 330, the equation becomes 330 = 90 + 4*60 = 90 + 240 = 330.

the numbers check out.

the service charge is 90.

the per hour charge is 60.

i believe your solution is that the electrician charges a flat fee of 90 plus an hourly fee of 60 for a service call.

1. (3 x 5) + (6 x 5) = (16 x 5) – (________ x 5) <br> 2. (3 x 8) + ( ________ x 8) = 13 x 8

Tcecarenko [31]

1. x3+x5=16. Multiply each side by 3: x+3x5=48. Continue simplifying and solving: 5x5+3x5=48. 8x5=48. 8x=240. x=30.

2. –7 x 8. –60. 3 ... You need to read the problem and know what information you (3 x 5) + (6 x 5) = (16 x 5) – (________ x 5(3 x 8) + ( ________ x 8) = 13 x 8
