Please help I’ll give brainiest!!
Answer:
x=-1
Step-by-step explanation:
You add like terms until you get your equation.
Answer:
x = -1
Explanation:
3(-1) - 10(-1) + 5 = 5(-1) + 17
-3 + 10 + 5 = -5 + 17
(add first before subtracting!)
12 = 12
So, the first answer, x = -1, is the correct answer.

26 - x = 17
What does x equal?
Answer: x = 9
We know that 26 and 17 are in a fact family.
Let's see the fact family.
26 - 17 = 9.
So, the answer is 9.
Hope this helps you!
Answer:
x = 9
Step-by-step explanation:
-x = 17 - 26 Take the numbers to one side and leave the letters on the other side
-x = -9 Subtract the numbers
x = 9 since the x and the 9 are negative they become positive
(two negatives equals a positive only when multiplying or
dividing and in this case you are dividing the -1x to both
sides)

A model of a house has been drawn on a coordinate grid. One corner of the house has been drawn at (6, 3). The drawing will be translated two units down and three units to the right. How should the translation be written?
Answer:
(9, 1)
Step-by-step explanation:
Given the coordinate of one corner of the house has been drawn at (6, 3), if the drawing is translated two units down and three units to the right
two units down = -2 (along the negative y axis)
three units to the right = +3 (towards the positive x-axis)
The coordinate used to translate the model of the house (x, y) is (3, -2)
Adding both coordinates:
= (x, y) + (6, 3)
= (x+6, y+3)
Substitute the values of the translated coordinates
= (3+6, -2+3)
= (9, 1)
The translation should be written as (3+6, -2+3) which is equivalent to (9, 1)

x-7(x-2)=10x+9-x
i need the answer asap pls
Step-by-step explanation:
x−7(x−2)=10x+9−x
Step 1: Simplify both sides of the equation.
x−7(x−2)=10x+9−x
x+(−7)(x)+(−7)(−2)=10x+9+−x(Distribute)
x+−7x+14=10x+9+−x
(x+−7x)+(14)=(10x+−x)+(9)(Combine Like Terms)
−6x+14=9x+9
−6x+14=9x+9
Step 2: Subtract 9x from both sides.
−6x+14−9x=9x+9−9x
−15x+14=9
Step 3: Subtract 14 from both sides.
−15x+14−14=9−14
−15x=−5
Step 4: Divide both sides by -15.
−15x−15=−5−15
x=13
Answer:
x=13

In a class of 40 students, every student take either Biology or Integrated Science, 30 students take Biology, 20 students take Integrated Science and 10 take both Integrated Science and Biology. Illustrate this information on a Venn diagram.
Answer
20 students will take biology, 10 take Integrated Science and 10 take both
Step-by-step explanation:
With Venn diagrams it's best you work from the inside out. With that in mind we know 10 students take both Biology and Integrated Science. In Biology there are 30 total students including the ones that also take both sciences. So we subtract the ones that take both and get 20 students taking only biology. After that there's 30 students total, subtract that from 40, the total number of students and you get 10, the amount of students who take Integrated Science
