Well you add +2 and +7 to both sides, which will cancel out on the left side but will make
4x+3x=60, or 7x=60. you're going to get a weird number, like 8.5714...
This should be a basic system of equations problem
-------------
12x + 4y = 152
32x + 12y =420
-----------------------
First solve 12x + 4y = 152 for x
Add -4y to each side
<span>12x+4y
+-4y</span>=<span>152
+-<span>
4y
</span></span>12x=-<span>4y+<span>152
</span></span>----------------------------
Divide each side by 12
12x ÷ 12 =
x = -1/3y + 38/3
============================================================
Substitute -1/3y + 38/3 for x in 32x+12y=<span>420
</span>32(-1/3y + 38/3)+12y=420
-------------
Simplify each side
4/3y + 1216/3 = 420
-------------------
Add -1216/3 on each side
4/3y + 1216/3
+ -1216/3 = 420
+ -1216/3
4/3y = 44/3
-------------------------
Divide each side by 4/3
4/3y ÷ 4/3 = 44/3 ÷ 4/3
y = 11
y = 11 is your answer
Answer:
x = 18 units
w = 20 units
n = 6.9 units
Step-by-step explanation:
Given: Similar figures
To find: value of the variable in each pair of similar figures
Solution:
Figures are said to be similar if they have same shape and not necessarily same size.
Corresponding sides of similar figures are always proportional.
Answer:
7/5 time 7/8 is exactly: 2 11/40
Step-by-step explanation:
Answer:
6 tulips
Step-by-step explanation:
First, we have to simply the ratio. The ratio for pansies to tulips would be 15:18, then simplifying it would make it 5:6 because the common factor is 3. 15 divided by 3 is 5 and 18 divided by 3 is 6. If you add 5 more pansies, it would equal 20 in total. Add 6 tulips because 6 plus 18 is 24. 20 divided by 4 is 5 and 24 divided by 4 is 6. That gives us a ratio of 5:6, which is the same from before. Therefore, you should add 6 tulips if 5 more pansies were added.
