Answer:
7
Step-by-step explanation:
22+54x=20+60x
54x=-42+60x
-6x=-42
x=7
Answer:
z = 3
Step-by-step explanation:
Similar polygons have the ratio of their corresponding sides equal to each other. There:
9/z = 6/2
Cross multiply
z*6 = 9*2
6z = 18
z = 18/6
z = 3
Answer:
-1/2
Step-by-step explanation:
pass (0,1) (2,0)
slope = rise/run = -1/2
Answer:
EX. 210/6
Step 1. Set up the equation, 210/6
Step 2. Divide the first digit/number 6 x 30 = 180 210 - 180 = 30
Step 3. rewrite the equation that is left, 30/6 6 x 5 = 30 30 - 30 = 0
Step 4. Only if need be for another equation, repeat step 1 and 2 until you have your answer
The Answer to the equation 210/6 is 35
Try 426/6 by yourself, please don't use a calculator.
I believe the answer would be (-3,-5).
Place the equations on top of each other and figure out how to cancel out one of the digits to get your answer. Try canceling out 2x. Multiply the entire equation y=x+3 by -2 to contradict the second equation. y=x(-2)+3(-2) then you'd get y=-2x-6. -2x-6 above 2x+1, solve. -2 and 2 cancel out so you're left with -6+1, therefore, y=5. Now that you have your y, you must solve for x. Using substitution to solve the equation (I picked 2x+1) you'd get -5=2x+1. Subtract 1 on both sides. +1-1=0 so that cancels out. -5-1=-6 and you're left with -6=2x. So you subtract 2 on both sides because 2 has the variable, and you are left with x=-3. Therefore, the answer is (-3,-5).
