Answer:

According to the question z must be equal to 4. So value of a+b=z or a+b=4

Lets try each of the options

A) a+b

1.6+2.3=3.9 which is not equal to 4

So option a is not the asnwer.

B) a+b = 1.6+2.5= 4.1 which is not equal to 4

<em>C) a+b= 1.9+2.1= 4.00 which is equal to 4</em>

<em />

D) a+b= 2.1+3.4= 5.5 which is not eqaul to 4

<u>Thus, we have OPTION C AS THE CORRECT ANSWER</u>

Trina planted plants in her garden last week. She planted twice as many cucumbers as zucchini and eight more tomatoes than cucum
maxonik [38]

Answer:

7 Zuchini, 14 Cucumbers and 22 Tomatoes plants.

Step-by-step explanation:

  • Let the number of tomatoes=t
  • Let the number of cucumber planted=c
  • Let the number of zucchini planted=z
  • Total Number of Plants=43

She planted twice as many cucumbers as zucchini, this is written as:

  • c=2z

She also planted eight more tomatoes than cucumbers, this is written as:

  • t=c+8=2z+8

In total, she planted 43 plants

Therefore:

z+(2z)+(2z+8)=43

5z+8=43

5z=43-8

5z=35

Divide both sides by 5

z=7

Number of Cucumbers, c=2z=2 X 7 =14

Number of Tomatoes, t=c+8=14+8=22

Therefore, she planted 7 Zuchini, 14 Cucumbers and 22 Tomatoes plants.

Novay_Z [31]

Answer:

the ounces of dough did you buy is 78

Step-by-step explanation:

The number of dough ounces that should be buy is given below:

There is a requirement of 6 dough ounces and 4 sauce ounces

So for each person it would be

= 4 + 6

= 10

Now the total ounces bought is 130

So, the number of people used

= 130 ÷ 10 ounces

= 13 people

Now let us assume the number of dough ounces be x

Now if there is 6 dough ounces and there are 13 people

So, the total dough ounces purchased is  

x = 6 × 13

= 78

Hence, the ounces of dough did you buy is 78

Lines N and Pare parallel. Angle M measures 126 degrees. Find the measure of angle Q.
DochEvi [55]

Answer:

Q= 126°

Step-by-step explanation:

Using the picture given, because these are parallel lines broken by a transversal, we can say the following

M=A=Q=F

B=C=D=G

Since, for example, M and C are the same line, we can say that M+C=180 and so on.

M=Q

Q= 126°
