Answer:

Yes

Step-by-step explanation:

The first one is 35+15 because 7*5 is 35 and 3*5 is 15

The second one is 45+5 because 9*5=45

35+15=50

45+5=50

Yes, they are equal.

Answer:Yes!

Step-by-step explanation:If you put 5 in every spot where the x varible is and solve the equations they both equal the answer.

7x+3x

7(5)+3(5)= 7 x 5=35, 3 x 5=15

35+15=50

9x+5

9(5)+5= 9 x 5= 45

45+5=50

Hope this helps!

Please help!! it says what I wrote is too short so

Answer:

50 cents The red on the right end.

Step-by-step explanation:

Let the chocolate chip cookies = x

Let the jumbo popcorn = y

Julie

y + 2x = 5

Marvin

y + 4x = 6 Subtract

-2x = - 1 The y's disappear. You are left with 1 dollar (negative). Divide by - 2

-2x/-2 = - 1 / -2

x = 1/2

x = 0.5 or 50c

Each cookie costs 50c

Tickets to a school play cost $2 if bought in advance and $3 at the door. By selling all 400 tickets, $1030 was collected. First

Marrrta [24]

Answer:

170 tickets.

Step-by-step explanation:

Write formulas for the question.

$N_2+N_3=400$

$2N_2+3N_3=1030$

Then use substitution.

$N_2=-N_3+400$

$2(-N_3+400)+3N_3=1030$

$-2N_3+800+3N_3=1030$

$N_3=230$

So number of $3 tickets sold is 230. But they ask for the tickets bought in advance (i.e. the tickets sold for $2). Use substitution again.

$N_2+230=400\\N_2=400-230\\N_2=170$

Help me on this question

olganol [36]

Answer:

see below

Step-by-step explanation:

All of the given data sets have x-values that are sequential with a difference of 1. That makes it easy to determine the sort of sequence the y-values make.

first choice: the y-values have a common difference of -2. This will be matched by a linear model.

second choice: the y-values have a common difference of +2. Again, this will be matched by a linear model.

third choice: the y-values have a common ratio of -2. This will be matched by an exponential model.

fourth choice: the y-value differences are 3, 5, 7, increasing by a constant amount (2). This is characteristic of a sequence that has a quadratic model.

Pls help me do absolute VALUE EQUATION 3/4I8t-12I=6(t-1)

mrs_skeptik [129]

There is no solution
Distributive property
3/4 x 8t - 12 x 3/4=6 x t - 1 x 6
6t - 9=6t - 6
The 6t being on both sides makes the answer. No solution.

Foot pieces you can cut from 5 feet of

Rzqust [24]

Answer:

1p = r

Step-by-step explanation:

You are asking how many 1-foot pieces you can make out of a 5 foot piece of ribbon. You are asking for an equation.

p = the # of pieces

r = the amount of ribbon

So lets try the equation:

1p = r

1(4) = r

1*4 = 4

4 = r
