Answers
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°

Answers
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.

this works because to find the middle of two numbers (in this explanation 10 and 20), you have to subtract the larger one from the smaller one (20 - 10 = 10) and take your sum and divide it by two (10 ÷ 2 = 5) and then add it back to the smaller number (5 + 10 = 15 = 1/2 the midpoint of 10 and 20)

Valeria already has $65 dollars in her savings account. If she puts $5 per week in her account, write and solve an inequality to find out how many weeks she must save to have at least $200 in her account.
Answers
Answer:
65 + 5x ≥200
Step-by-step explanation:
Hi, to answer this question we have to write an inequality with the information given:
Janice's savings (65) plus the product of the amount she saves per week (5) and the number of weeks (x) must be higher or equal to $200.
Mathematically speaking:
65 + 5x ≥200
If we solve it for x:
5x ≥200-65
5x ≥135
x ≥ 135/5
x ≥ 27 weeks

Answers
Answer:
They are different because in the mantle, the magma is heated, it becomes less dense and rises. It give off it's thermal energy and cools down, becoming more dense and descend to be heated again.
In the ocean, the tropics warm the water and it travels to the poles to cool down, then returns to the tropics to heat up again.

2. 200.52 4. 212.67 5. 148.48
Step-by-step explanation:
for (2) you find the area of each shape first the square
12*12=144
then you find the area of the semicircle
the formula is A= (3.14)r^2/2
the (r) is 6 because that is half of the whole side of the semicircle
so... (3.14) 6^2/2
6*6= 36
(3.14)36/2
113.04/2
56.52
then add the 144 from the square to it
56.52+144
200.52

Answer:
From 12 o'clock position clockwise:
-12
-1
11
12
Step-by-step explanation:
y = -1 (given).
x + y = 11
Plug in -1 for y in the equation (given):
x + (-1) = 11
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 1 to both sides of the equation:
x - 1 (+1) = 11 (+1)
x = 11 + 1
x = 12
x + y = ?
x = 12
y = -1
Plug in the corresponding numbers to the corresponding variables:
12 + (-1) = 12 - 1 = 11
xy = ?
x = 12
y = -1
Plug in the corresponding numbers to the corresponding variables. Note that when you multiply a negative and a positive number, your answer will be negative:
12 * -1 = -12

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
Desiree has $36 in her bank account. She spends $14.50 on dinner and tickets to a basketball game.
