Answer:
$3
Step-by-step explanation:
Plug in 2 for y, so you get 2x + 3(2) = 12, and that simplified would be
2x + 6 = 12. Next, subtract 6 from both sides, so you get 2x = 6. Divide 2 by both sides to get 3!

Last year the depth of the river was 4.2 feet deep.
This year it dropped 19%.
Find the depth of the river this year to cross it.
Answer:
3.402
Step-by-step explanation:
If it dropped 19% that means it is only 0.81 of the depth last year. Multiplying 0.81 by 4.2 gives 3.402.

Ava is a high school basketball player in a particular game she made some three point shots and some two point shots Ava made a total of 12 shots altogether and scored a total of 28 points how many of the points were three points and how many were 2 points
Answer:
Ava made 4 three point shots and 8 two point shots.
Step-by-step explanation:
Let X represent the number of 3-point shots and Y represent the number of 2-point shots.
Then using the provided data two equations can be formed:
X + Y = 12...(i)
3X + 2Y = 28...(ii)
Solve (i) and (ii) simultaneously:
Multiply (i) by 2 and subtract (ii) from (i) as follows:
2X + 2Y = 24
-3X - 2Y = -28
-X = -4
X = 4
Substitute X = 4 in (i) and solve for Y as follows:
X + Y = 12
4 + Y = 12
Y = 8
Thus, Ava made 4 3-point shots and 8 2-point shots.

Which reason best explains why living things need carbon?
Carbon bonds are a source of energy.
Carbon levels reduce global temperatures.
Carbon acts as an important solvent.
Carbon is everywhere.
Answer:
Carbon Bonds are a source of energy
Step-by-step explanation:
If this were a free answer response question, I would say that the reason would be that carbon can form bonds with many other element, but it wasn't there, so the first option is the closest to my answer.

Convert 8/9 to its decimal form and round to the nearest thousandth
To figure out what a fraction is as a decimal u would do the top divided by the bottom
For this fraction it would look like this,
8 divided by 9 which would get you 0.88888888888
So your decimal is 0.889
Its not 0.888 because with decimals since a typical decimal is show as 2-3 numbers it would be rounded up to keep it as 3 numbers or less. so this would be 0.889 or if that doesnt work 0.888 with a line over the last 8.
Answer:
0.889
Step-by-step explanation:
0.88888888 repeating the 3rd 8 is the thousandth place so you look at your neighbor and it is 5 or higher so you round up to 0.889
In parallelogram ABCD, the measure of angle A=3x and the measure of angle B =x+10. What is the measure of angle D?
Answer: 52.5
Step-by-step explanation: 2(3x+10)+2(x+10)=360 because all the sides of a rhombus equal 360 and alternate sides are equal
8x+20=360
-20=-20
8x/8=340/8
x=42.5
x+10. 42.5+10=52.5
D=52.5
The measure of ∠D in parallelogram ABCD is 52.5°.
What is a parallelogram?A parallelogram is a 2D figure in which opposite sides are equal.
We know in a parallelogram sum of the adjacent angles is 180° and opposite angles are equal.
∴ In a parallelogram, ABCD ∠A = ∠C and ∠B = ∠D and we also know that sum of all the interior angles of a parallelogram is 360°.
∴ ∠A + ∠B + ∠C + ∠D = 360°.
2∠A + 2∠B = 360°.
2(3x) + 2(x+10) = 360°.
6x + 2x + 20° = 360°.
8x = 340°.
x = 42.5°.
Given, ∠B = ∠D = x + 10° = 42.5° + 10° = 52.5°.

A. X-4, 7-8
B. x - 7,7=43
C. x = 4√3, 7-72
D. x=753, y = 4√2
Answer:
[tex]x= 7, y=4\sqrt{2}[/tex]
Correct option B.
Step-by-step explanation:
The diagram shows a trapezoid with a base angle of 45° and the other base angle of 90°.
We have completed the diagram to draw a perpendicular line over the base of height h=4. A triangle is formed with an angle of 45°.
Recall a right triangle with angles of 45° is isosceles, thus the base and the height are h=4. Please check the diagram below.
For that triangle, we apply Pythagora's Theorem:
[tex]y^2=4^2+4^2=2*4^2[/tex]
Thus:
[tex]y=\sqrt{2*4^4}=4\sqrt{2}[/tex]
[tex]y=4\sqrt{2}[/tex]
The base of the trapezoid x is h + 3 = 7
Thus:
[tex]\mathbf{x= 7, y=4\sqrt{2}}[/tex]
Correct option B.
