Answer:
360cm
Step-by-step explanation:
The top square is 10 x 13 = 130
The middle square is 10 x 12 = 120
Both side triangles are 5 x 12 = 60. You would halve it but there are two triangles.
5 x 10 = 50
50 + 120 = 170
170 + 130 = 300
300 + 60 = 360
Equation would be (10 x 13) + (10 x 12) + (5 x 12/2) + (5 x 12/2) + (10 x 5)
The equation options seem like they are missing some numbers or something

Step-by-step explanation:
If you need this as a fraction then the answer is probably 1 9/10
Answer:
x = 1.5
Step-by-step explanation:
We need a value of x that would result in 2x+9 = 12
2x+9 = 12
2x = 12 - 9
2x = 3
x = 3/2 or 1.5
====
CHECK
Does 2x+9 = 12 when x = 1.5?
2x+9 = 12
2(1.5)+9 = 12
3 + 9 = 12 YES
Answer:
<em>Bot ratios are equivalent? YES</em>
Step-by-step explanation:
The Semi Scooper Sundae has 10 scoops of ice cream and 6 cherries. The ratio of cherries to scoops of ice cream is:
Simplifying:
Ratio= 3:5
The Super Scooper Sundae has 15 scoops of ice cream and 9 cherries. The ratio of cherries to scoops of ice cream is:
Simplifying:
Ratio= 3:5
Bot ratios are equivalent? YES
Answer:
x = -2, y = 3
Step-by-step explanation:
Given equations are,
4x + 5y = 7 ---------(1)
3x - 2y = -12 ----------(2)
Multiply equation (1) by 3
12x + 15y = 21 ------(3)
Multiply equation (2) by (-4)
-12x + 8y = 48 --------(4)
Now add equations (3) and (4),
(12x + 15y) + (-12x + 8y) = 21 + 48
(12x - 12x) + (15y + 8y) = 69
23y = 69
y = 3
From equation (2),
3x - 2(3) = -12
3x - 6 = -12
3x = 6 - 12
x = -2
Therefore, x = -2 and y = 3 will be the answer.
