Please help. You will get some points.
Answer:
1) x: small #; y: large #
4y = 7x
x + y = 22
----------------
-7x + 4y = 0
x + y = 22
---multiply the second equation by -4------
-7x + 4y = 0
-4x - 4y = -88
----solve------
-11x = -88
x = 8
---substitute with any of the equation above i chose the very first one------
4y = 7(8)
4y = 56
y = 14
x = 8; y = 14
2) x = small #; y = large #
y - x = 15
5x = y - 9
----after rearranging, solve-----
-x + y = 15
5x - y = -9
-4x = 6
x = -1.5
--------substitute--------
-(-1.5) + y = 15
1.5 + y = 15
y = 13.5
x = -1.5; y = 13.5
3) x = lemon cream; y = fudge cookie
3x + 2y = 400
2x + 3y = 425
----multiply the first equation by -2, multiply the second equation by 3------
-6x - 4y = -800
6x + 9y = 1275
----solve------
5y = 475
y = 95
--------substitute--------
3x + 2(95) = 400
3x + 190 = 400
3x = 210
x = 70
x = 70; y = 95

The complement of the angle is 1/2 of the measure of the angle. Find the measure of the angle.
Group of answer choices
1.180°
2.90°
3.60°
4.30°
Answer:
choice 2) x = 60°
Step-by-step explanation:
the complement of an angle is an angle that when added to the original angle = 90°
so:
x + 0.5x = 90°
1.5x = 90°
x = 90/1.5 = 60°
Find the area of the triangle. Round your answer to the nearest 10th.
6
2
Answer:
6 or possibly 6.0
Step-by-step explanation:
The area of a triangle is equal to the height x base divided by 2, which is basically h × w ÷ 2. So it's 2 × 6 ÷ 2, which equals to 6. If rounded, it should possibly be 6.0.
Two questions can you please answer correctly.
Answer:
First question: D. 6.28 ft
Second question: C. Rectangle
Step-by-step explanation:
The circumference of the circle is 6.28 ft. The first thing you do to find the circumference for this circle is find what the radius is. Since the diameter is equal to 2 times radius, and the diameter is 2, we know that the radius is one. Now, we can find the circumference. To find it, the formula is 2 times π times radius. For this problem, we use π for 3.14 and the radius for 2. In this case, 2 times 3.14 times 1 is equal to 6.28. Therefore, the circumference of this circle is equal to 6.28.

Answer question 17 and I will give you brainlest. The second photo is what you need to use to answer the question.
Answer: 23°
Step-by-step explanation:
First, we need to find the missing angle to the left of x
Let's take what we are given
which is 130°, As you notice the angle of 130° is on a straight line
A straight line is supposed to equal 180°
So we can take 180°-130° which will equal 50°
Now we know that the missing angle next to x is 50°
Now we need to take 107° and add it to 50
Which will equal 157°
Now to get x, we need to take 180°-157°
Which will equal 23°
x=23°

(no links)
Step-by-step explanation:
Alright,
Multiply each side by each other so,
16×5 = 80
80×4.5= 360
360× 12 = 4,320
4,320 × 21 = 86,400
The area of this figure is 86,400. I Hope this helps you ^-^ ♡
I need help with math
Answer:
The missing angle is 70 Degrees.
Step-by-step explanation:
You have a 9 degree angle on the opposing side making the complete angle of the missing one plus the 20 degrees 9 degrees. Now simply subtract your 20 degrees from the 90. =70
Answer: 110°
Step-by-step explanation: The missing angle is an obtuse angle which means that this angle is greater than 90° but less than 180°
