Answer:

Step-by-step explanation:

29 years they are combined ages the same and if this goes up 2:1 ratio every year thereafter from age 43 then to change 29:43 to make double it is x 8 43 x 8= 344 and  29 x16=464. The ages never become double.

the point B(-3, -2) is translated 4 units left. what are the coordinates of the resulting point, B’?
ololo11 [35]

Answer:

B'(-7 , -2)

Step-by-step explanation:

First we must understand the coordinate-axis, when we want to move a point to the left or right we do it on the x-axis. to move up or down is on the y axis.

now if we move to the left we go to the negative and to the right the positive

as we are going to move to the left we have to subtract the value that he gave us (4) only to the part of x

B(-3 , -2)

-3 - 4 = -7

B'( -7 , -2)

In a test (+5) marks are given for every correct answer and (-2) marks are given for every incorrect answer. Smitha answered all
Ymorist [56]

Answer:

15 answers

Step-by-step explanation:

To solve this question we need to set up an equation.

Let's name the number of incorrect answers x.

<u>We can set up an equation that's essentially:</u>

(Points for correct answer)*(number of correct answers)+(points for incorrect answer)*(number of incorrect answers)=final score

When we plug in our numbers and variables it looks like this:

5(3)+(-2x)=-15

Simplify

15-2x=-15

Subtract 15 from both sides

-2x=-30

Divide both sides by -2

x=15

This means Smitha attempted 15 wrong answers, and that there were 18 questions in total.
