Portfolio help

Answer 1

I will take any help at all

Answer 2

for the first one, if she made $65 and worked for 4 hours at $8 per hour i would say
\[65=4\times 8+t\]

Answer 3

actually i would say
\[65=32+t\] but that was not a choice

Answer 4

second one is the distributive law

D. Jamie multiplied 3x and 7 by -5 to eliminate the parentheses. This procedure is justified by the distributive property.

kind of a weird way to word it, but it is the best of the choices

Answer 5

:) thank you

Answer 6

for the third one, since \(x\) is the number of hot dogs and \(y\) is the number of hamburgers, and since (2, 1) is a solution, means he bought 2 hot dogs and 1 hamburger

Answer 7

fourth one you have to solve
15x + 10y = 700
x + y = 60

Answer 8

you can write the second equation as \(y=60-x\) and so substituting in to the first equation you get
\[15x+10(60-x)=700\] and you can solve that for \(x\)
do you know how to do that?

Answer 9

no

Answer 10

multiply out using the distributive law first, get
\[15x+600-10x=700\] combine like terms to get
\[5x+600=700\] subtract 600 from both sides gives
\[5x=100\] then divide both sides by 5

Answer 11

this should look more or less familiar

Answer 12

so b and it looks familiar

Answer 13

ok wat about 5?

Answer 14

is it the same thing or no?

Answer 15

more or less
solve
5x + 4y = 32
x + 6y = 22

Answer 16

in this case you can write
\[x=22-6y\] and solve
\[5(22-6y)+4y=32\] similarly

Answer 17

\[110-30y+4y=32\]
\[110-24y=32\]
\[-24y=-78\] divide by -24

Answer 18

sixth one solve \[51 = 6h + 15\] in two steps

Answer 19

then for part B solve \[ 6h + 15 = 8h + 9\] for \(h\)

Answer 20

subtract \(6h\) from both sides to get
\[15=2h+9\] subtract 9 to get \[6=2h\] then divide by 2

Answer 21

OK :) I got that thats was easy thank you :)

Answer 22

yw

Answer 23

can yuh help me with the rest please? if not its totally fine

Answer 24

for C it looks to me like alex will have more money than pat after 5 hours
it is hard for me to read it exactly, but it looks like at 5 hours the solid line is higher than the dotted one

Answer 25

it is

Answer 26

ok good, so the answer is \(h> 5\)

Answer 27

for the next one if \(y\) is the height, than you can see that 4 additional bowls add an additional 3 inches
one bowl gives you 2 inches
you can use
\[y=\frac{3}{4}(x-1)+2\] if you like where \(x\) is the number of bowls

Answer 28

then if you want to know the hight with 10 bowls compute
\[y=\frac{3}{4}(10-1)+2\]
you will get a mixed number or a fraction

Answer 29

ok thank you so much :) I have another portfolio... will u help if no I understand and ur help is greatly appreciated
