3. Basket A had 7 times as many plums as basket B at first. Zoe put 58 more plums in each
asambeis [7]

Answer:

87 many more plums are there in Basket A than Basket B

Step-by-step explanation:

Before

N = 58/2

Basket A = N x 7 + 58

Basket B = N x 7

Now

Basket A = 29 x 7 + 58

= 261/3

= 87

Basket B =  29 x 7

= 203 + 58

= 261/3

= 87

Basket A and B has a difference of 87 Plums

:) Thank you!!

What is y= -2/3x + 5 written in standard form?
GaryK [48]

1) the standar form of the  equation is  ax+by  = c, therefore, for  y = -2/3x+5, multiply by 3 the previous equation, and its result is  3y = -2x+15⇒ 3y +2x = 15

the final result is  2x+3y = 15

When solving the linear equation, ax + b = 0 where a≠ 0, what is the answer of the equation x = -b/a referred as?
Oksi-84 [34.3K]

In a system of equations ax + b = 0, a≠ 0, the equation x = -b/a is referred as a non-trivial solution.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

The system Ax + b = 0 has the following solutions:

  • The zeros, which is the trivial solution.
  • x = -b/a, which is the non-trivial solution.

Determine the measure of angle a. PLEASE HELP ASAP!
wlad13 [49]

Answer:

D

Step-by-step explanation:

Remember that the sum of the interior angles of a triangle will always total 180.

Therefore:

(9x+6)+(74)+(16x)=180\\

Let’s solve for <em>x: </em>

Combine LIke Terms:

(9x+16x)+(74+6)=180

Add:

25x+80=180

Subtract 80 from both sides:

25x=100

Divide both sides by 25:

x=4

Therefore, the value of <em>x </em>is 4.

Now, to find A, we can substitute it for A.

A is measured by:

\angle A=9x+6

Substitute 4 for <em>x</em> and evaluate:

\angle A=9(4)+6=36+6=42\textdegree

Hence, our answer is D.
