Answer:
15° and 100°
Step-by-step explanation:
3 × 5 = 15, 20 × 5 = 100. So the other two angles measure 15° and 100°.
Not sure but think A=1, X=2, Y=3.If this is for a grade try to work it out some but these numbers work when they sre plugged in where they sre sippose to be.
Answer:
78 ml of 7% vinegar and 312 ml of 12% vinegar.
Step-by-step explanation:
Let x represent ml of 7% vinegar brand and y represent ml of 12% vinegar brand.
We have been given that chef wants to make 390 milliliters of the dressing. We can represent this information in an equation as:
We are also told that 1st brand 7% vinegar, so amount of vinegar in x ml would be .
The second brand contains 12 vinegar, so amount of vinegar in y ml would be .
We are also told that the chef wants to make 390 milliliters of a dressing that is 11% vinegar. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, the chef should use 78 ml of the brand that contains 7% vinegar.
Upon substituting in equation (1), we will get:
Therefore, the chef should use 312 ml of the brand that contains 12% vinegar.
Answer:
D'F' = 28
Step-by-step explanation:
For the vertex D(1, 1)
D'(1 × 7, 1 × 7) = D'(7, 7)
For the vertex E(1, 5)
E'(1 × 7, 5 × 7) = E'(7, 35)
For the vertex F(5, 1)
F'(5 × 7, 1 × 7) = C'(35, 7)
Now to find the D'F':
we do:
y2 - y1 =
and
x2 - x1 =
Here are what the numbers mean
x1 = 7
y1 = 7
x2 = 35
y2 = 7
For the points above (7,7) and (35,7), in which (7,7) is Point 1 and (35,7) is Point 2:
Find the distance along the y-axis.
y2 - y1 = 7 - 7
7 - 7 = 0
Find the distance along the x-axis.
x2 - x1 = 35 - 7
35 - 7 = 28
Now we do: y² and x²
y² = 0² = 0
x² = 28² = 784
Next we add the y and x
0 + 784 = 784
And lastly, we do √x + y
Which is the same as: √0 + 784
√0 + 784 = 28
So the answer is 28

Answer:
5
Step-by-step explanation:
Simplifying
8 + 4 = 2(x + 1)
Combine like terms: 8 + 4 = 12
12 = 2(x + 1)
Reorder the terms:
12 = 2(1 + x)
12 = (1 * 2 + x * 2)
12 = (2 + 2x)
Solving
12 = 2 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, and all other terms to the right.
Add '-2x' to each side of the equation.
12 + -2x = 2 + 2x + -2x
Combine like terms: 2x + -2x = 0
12 + -2x = 2 + 0
12 + -2x = 2
Add '-12' to each side of the equation.
12 + -12 + -2x = 2 + -12
Combine like terms: 12 + -12 = 0
0 + -2x = 2 + -12
-2x = 2 + -12
Combine like terms: 2 + -12 = -10
-2x = -10
Divide each side by '-2'.
x = 5
Simplifying
x = 5
