Can someone pls help me? I dont feel like going back to look at my questions lol.
Answer:
10
Step-by-step explanation:
for the smoll triangle, u multiply 2x2 and divide it by two which is 2 and then u solve for the square which is 2x2= 4 and then u solve for the big triangle which is 4x2 and you divide it by 2 which is 4 and you add them together which is 10
The equation 2x + 2 = x+5 is modeled below. x What value of x makes the equation true? A X = 1 B Y = 3 C x = 5 D X = 7
Answer:
b
Step-by-step explanation:
2x + 2 = 1x + 5
combine the like terms.
2x + 2 = 1x + 5
-2x -2x
------------------
2 = -1x + 5
isolate the -1x.
2 = -1x + 5
-5 -5
----------------
-3 = -1x
solve for x.
-3/-1 = -1x/-1
3 = x
so b. correct me if any of this is wrong.

Group of answer choices
12/13
13 to 12
12 to 13
13:25
Answer:
13 to 12
Step-by-step explanation:
Since we're supposed to find the ratio of girls to boys, then let's make a ratio! Remember since they said girls first, we have to start with the number of girls. Since they said boys first, we have to end with the number of boys.
girls to boys
That is our ratio. Now let's plug in the number of girls and boys!!
Girls = 13
Boys = 12
13 to 12
The answer is 13 to 12.

4x + 10 = -26
Subtract 10 from both sides
4x = -36
Divide each side by 4
x = -9
To check it, substitute -9 for x in the original equation.
4(-9) + 10 = -26
-36 + 10 = -26
-26 = -26
Answer:
X=-9
Step-by-step explanation:
4x+10=-26
4x=-26-10
4x=-36
x=-9

5>9 ,, false
5<18,, true
5>42,, false
Answer:
C

A isn’t correct because it says 5<2, 5 is less then 2, which isn’t correct. B isn’t correct because it says 5>9, 5 is greater then 9, which isn’t correct. C is correct because it says 5<18, 5 is less then 18, which is correct. D isn’t correct because it says 5>42, 5 is greater then 42, which isn’t correct.

Answer:
C
Step-by-step explanation:
We need to find the area of BOTH the rectangle AND the triangle. So the formula to find area of a triangle is bh[tex]\frac{1}{2\\}[/tex], or bh/2
b- base
h height
And obviously to find area of rectangles and stuff like that is just l x w
So let's find area of the rectangle, AKA the whole,
5x11=55
The area of the rectangle is 55
Now for the triangle,
The base is 5, and the height is 3. 5 x 3 = 15, and 15/2 = 7.5
The area of the triangle is 7.5
Now, subtract because we don't want the area of the triangle BUT the shaded region, so 55-7.5= 47.5 We have to add a unit so its 47.5^2, so the answer is C
Hope this helps!!
