Add 2x + 5 and 4x - 7
Then you isolate the variable or “get rid of” the numbers that re stopping you from getting “x”.
By doing the inverse operation.
If you add ___ you subtract ____ it form itself
If you subtract ___ you add ____ To itself.
So you Cancel out by getting rid of the other numbers.
Same thing with multiplying and dividing.
If you multiply ____ you divide___ but don’t divide “x”
Only the integer.
If you divide _____ you multiply ____ it
Number of pounds of cashews is 36 pounds and number of pounds of walnuts is 4 pounds.
Step-by-step explanation:
- Step 1: Given details are cost of cashews = $1.58, cost of walnuts = 78 cents = $0.78, total weight of nuts = 40 pounds, cost of nuts per pound = $1.50
- Step 2: Let number of pounds of cashews to be mixed be C, then number of pounds of walnuts will 40 - C. Form equation with these variables.
⇒ 1.58 C + (40-C) 0.78 = 40 × 1.50
⇒ 1.58 C + 31.2 - 0.78 C = 60
⇒ 1.58 C - 0.78 C = 60 - 31.2
⇒ 0.8 C = 28.8
⇒ C = 36 pounds
- Step 3: Calculate number of pounds of walnuts
⇒ Number of pounds of walnuts = 40 - C = 4 pounds
I believe it would be the last answer, 6.25
if this is correct i’m very sorry, but if this helps, please mark brainliest. :)
Take a picture of the table
To solve for S, you would want to get rid of the denominator so multiply 360 onto both sides. then the equation is 360A=pi times r squared times S. Divide both sides by pi and r squared and you get S=360A/pi times r squared
