Answers

20 p per pear 10p per peach

Step-by-step explanation:

Hope this helps

Answer 2

Answer:

1 pear costs 20 cents. 1 peach costs 10 cents.

Step-by-step explanation:

x represents pears

y represents peaches

4x + 2y = 1

2x + 3y = 0.7

multiply the second equation by -2 to elimate the x variable

(2x +3y = 0.7) -2 = -4x - 6y = -1.4

add the new equation to the first original one:

4x + 2y = 1

-4x - 6y = -1.4

-4y = -0.4. divide both sides by -4, y = 0.10

plug in y = 10, solve algebraically and get x = 0.20

Lastly, check your work:

4(0.20) + 2(0.10) = 1

2(0.20) + 3(0.10) = 0.7

if y=3 then 14y equals

Answers

Answer:

42

Step-by-step explanation:

14(3)

Answer:

42

Step-by-step explanation:

first, substitute 3 for y in 14y. 14y means you are multiplying 14 and y, so when you plug in 3 for y, you're multiplying 14 and 3! :)

14y ⇒ 14(3)

simplify by multiplying 14 · 3.

14(3) = 42

so, when y = 3, 14y = 42.

you can check the answer by solving for y in 14y = 42.

divide both sides of the equation by 14.

14y/14 = 1y or y42/14 = 3

after dividing, you're left with y = 3. that means 14y does indeed equal 42 when y = 3! :)

i hope this helps! have a great rest of your day <3

True of flase a point (0,2) can be reflected across the x-axis PLEASE HELP 50 POINTS​

Answers

Answer:

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).

So what do you think the answer is true or false

Answer:

True

Step-by-step explanation:

That is possible since the x is on 0. It can flip and then it lands on (0,-2) I think.

The measure of angle Q is 70 degrees. Find the measure of angle P.

Answers

Answer:

∠ P = 40°

Step-by-step explanation:

Since PQ = PR then the triangle is isosceles and the base angles are congruent, then

∠ R = ∠ Q = 70° , so

∠ P = 180° - (70 + 70)° ← sum of angles in triangle is 180°

∠ P = 180° - 140° = 40°
