Answer:
(x, y) = (7, 2 2/3)
Step-by-step explanation:
We can multiply the first equation by 2/5 to get ...
8x -6y = 40
The second equation gives an expression for 6y that we can substitute.
8x -(3x -5) = 40
5x +5 = 40 . . . . . eliminate parentheses
x +1 = 8 . . . . . . . .divide by 5
x = 7 . . . . . . . . . .subtract 1
Using the second equation, we find ...
3(7) -5 = 6y
y = 16/6 = 2 2/3
The coordinates of the point of intersection are (x, y) = (7, 2 2/3).

Heather has a thin piece of wood that measures 14 inches long by 13 inches wide. She wants to make a box with a height of 3 inches. Heather says that she has enough wood to make a box that has bases measuring 6.5 inches by 6.5 inches. Do you agree?
Answers
Answer:
Yes, I agree. Since the area of the piece of wood is greater than the area of the box she wants to make, then she has enough wood to make the box.
Step-by-step explanation:
First, we will calculate the area of the piece of wood Heather has
Area (A) = Length (l) × Width (w)
From the question, l = 14 inches and w = 13 inches
A = 14 inches × 13 inches
A = 182 squares inches
Hence, the area of the piece of wood is 182 square inches
Now, we will calculate the total surface area of the box she desires to make
Area (A) of a box is given by
A = 2lw + 2lh + 2wh
Where l is the length
w is the width and
h is the height
She wants to make a box with a height of 3 inches and bases measuring 6.5 inches by 6.5 inches.
i.e h = 3 inches, l = 6.5 inches and w = 6.5 inches
∴ A = 2(6.5×6.5) + 2(6.5×3) + 2(6.5×3)
A = 84.5 + 39 + 39
A = 162.5 square inches
Hence, the area of the box she wants to make is 162.5 square inches
Since the area of the piece of wood is greater than the area of the box she wants to make, then she has enough wood to make the box.

Osvoldo has a goal of getting at least 30, percent of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of carbohydrates, and 55 grams were from whole grains.
Answers
Answer:
No
He ate only 25% from whole grains
He ate 5% less grams from his goal
Step-by-step explanation:
Osvoldo has a goal of getting at least 30, percent of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of carbohydrates, and 55 grams were from whole grains.
Did Osvoldo meet his goal? Why? , Osvoldo ate grams of whole grains than his goal.
Percent of whole grains ate = grams of whole grain / total carbohydrates) x 100
(55/220) x 100 = 25%
This is less than his goal of 30% by (30% - 25%) 5%
Answer:
No, Osvoldo 11 grams of whole grains less than his goal.
Step-by-step explanation:
30% x 220
30% = 30/100 = 30 ÷ 100
30 ÷ 100 = 0.3
0.3 x 220 = 66
66 - 51 = 11

Choose the equation below whose axis of symmetry is x = 2. (1 point)
O y=x²-2
O y = x2 - 4x + 2
O y = x2 + 4x + 2
O y=x²-4
Answers
Answer:
y = x2 - 4x + 2 ; y=x²-4
Step-by-step explanation:
Axis of symmetry = - b /2a
y=x²-2
a = 1 ; b = - 2
x = - (-2) / 2(1)
x = 2/2 = 1
y = x2 - 4x + 2
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
y = x2 + 4x + 2
a = 1 ; b = 4
x = - 4 / 2(1)
x = - 4/2 = - 2
y=x²-4
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
Answer:
y = x2 - 4x + 2 ; y=x²-4
