Answer:
For the first question the answer is 50(0.2 + 1)^2 = 72
For the second question it is y = 32
Step-by-step explanation:
In case you need to see how i got it...it's below
For number 1, y is proportional to (x + 1)^2
The equation would be y(x +1)^2 = k(the constant). Then I substituted numbers you gave me in the equation which was : 50(0.2 + 1)^2 = k(72)
For number 2 I used this equation: y (x + 1)^2 = 72. I substituted x for 0.5. The equation will be: y(0.5 + 1)^2 = 72. Then I got 32 for y.
Hope this helps:)

Each serving for a box of trail mix is 3/8 of a cup.
Enter the number of 3/8 -cup servings there are in 1 1/2 cups of trail mix.
Answer:
It's 4
Step-by-step explanation:
It asks how many 3/8 cups are in 1 1/2 cups. So, we divide.
1 1/2 ÷ 3/8. We have to change the 1 1/2 into a improper fraction. 1 1/2 = 3/2. 3/2 ÷ 3/8 = 3/2 ÷ 8/3 = 24/6. Simplify, and you get 4. :)

Guess and check (using the multiple choice answers):
F: 12 + 13 / 32 + 13 = 25/45 = 5/6; does not equal 3/5
G: 12 + 18 / 32 + 18 = 30/50 = 3/5; does equal 3/5
H: 12 + 28 / 32 + 28 = 40/60 = 2/3; does not equal 3/5
J: 12 + 32 / 32 + 32 = 44/64 = 11/16; does not equal 3/5
K: 12 + 40 / 32 + 40 = 52/72 = 13/18; does not equal 3/5

Ed buys a box of eggs costing £2.80, two packs of bacon for £2.40 each and two tins of baked beans. He pays with a £10 note and gets 80p change. How much does a tin of beans cost in pounds, £?
Answer:
£0.8
Step-by-step explanation:
egg = 2.80
Bacon = 2 * 2.40 = 4.80
Baked beans = 2 tins
Amount issued = 10
Change obtained = 80p = 0.8
Let cost per baked beans = x
Hence,
2.80 + 4.80 + 2x = 10 - 0.8
7.60 + 2x = 9.20
2x = 9.20 - 7.60
2x = 1.6
x = 1.6 / 2
x = 0.8
Hence, a tin of baked beans cost £0.8
Answer:
£0.80
Step-by-step explanation:
egg = 2.80
Bacon = 2 * 2.40 = 4.80
Baked beans = 2 tins
Amount issued = 10
Change obtained = 80p = 0.8
Let cost per baked beans = x
lol
2.80 + 4.80 + 2x = 10 - 0.8
7.60 + 2x = 9.20
2x = 9.20 - 7.60
2x = 1.6
x = 1.60 / 2
x = 0.80
YES WE GOT IT, a tin of baked beans cost £0.80

Step-by-step explanation:
Someone pleaseee help meeeee :( ???? On this.
Answer:
A. 9
Step-by-step explanation:
To solve slope with points, use the equation: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]. In this case it would be: [tex]\frac{7 - (-2) }{-6- (-7) }[/tex]. 7 - -2 is also 7 + 2 or 9. -6 - - 7 is also -6 + 7 or 1. So the final fraction is [tex]\frac{9}{1}[/tex] or 9.
Hope it helps!

Number 13 Find the measures of angles 1, 2, and 3.
Answer:
1. 37
2. 26
3. 26
Step-by-step explanation:
Subtracting 63 from 180, you find the linear pair, being 117 which helps find an angle in the lower triangle. The sum of all angles is 180, and to find 2, you subtract the known angles ( 180-(37+117)) which equals 26. Knowing the shape is a parallelogram, and the opposite sides are parallel, we can say 2 and 3 are congruent through the alternate interior angles theorem. 1 is found through applying the same theorem.

Which variable should an expression be substitute for?
9514 1404 393
Answer:
x
Step-by-step explanation:
There is already an expression given for x, so that is the easiest variable to substitute for.
Substituting for x using the second equation, you have ...
-3(-2y+14) +y = -14
6y -42 +y = -14
7y = 28
y = 4
x = -2(4) +14 = 6
The solution is (x, y) = (6, 4).
_____
Substitution for x is the easiest.
__
The first equation could be rearranged to give an expression for y:
y = 3x -14
Then that can be used to substitute for y in the second equation. My lazy brain judges that to be more work.
