The answer is c. I’ve seen this question before
Step-by-step explanation:
step 1. 17/21 - 2/10 = x (in order to subtract you need a common denominator)
step 2. (17/21)(10/10) - (2/10)(21/21) = x
step 3. 170/210 - 42/210 = x
step 4. 128/210 = 64/105 = x
step 5. x = 64/105.
Answer:
The answer is 6.
Step-by-step explanation:
You need to have side x + 4 equal side 3x - 8. If you plug 6 into both equations, then you get x + 4 = 910and 3x - 8 = 10. The last side of the triangle equals 6. You then add all three sides together to get 25. 10 + 10 + 5 = 25.

Answer:
x= -2
Step-by-step explanation:
suppose,
the number is x
so,
Four more than 6 times a number = 6.x+4=6x+4
9 times the number increased by 10 =9x+10
Now,
6x+4 = 9x+10
⇒9x-6x=4-10
⇒3x=-6
⇒x=- 6/3 [divide both sides by 3 ]
⇒x= -2
