1/7 = -3/2w -4/5
add 4/5 to both sides
1/7 + 4/5= -3/2w
change to common denominator; 5 & 7 go into 35
(1*5)/35 + (4*7)/34= -3/2w
5/35 + 28/35= -3/2w
33/35= -3/2w
divide by -3/2 on both sides; multiply by the reciprocal of -3/2
33/35 * -2/3= w
-66/105= w
simplify by 3
-22/35= w
CHECK:
1/7 = -3/2w - 4/5
1/7= -3/2(-22/35) - 4/5
1/7= 66/70 - 4/5
1/7= 66/70 - 56/70
1/7= 10/70
1/7= 1/7
ANSWER: w= -22/35
Hope this helps! :)
That dot means multiplication
Answer:
length = 194 (97+97)
Step-by-step explanation:
p= 312 width= 59
= 59×2-312
= 118 - 312
= 194
Answer:
28.26
Step-by-step explanation:
A = r^2
So the equation is. Area of circle = pi(3.14) * radius(3) to the power of 2 (^2)
A = 3.14(3)^2
A = 3.14(9)
A = 28.26
This is one way you could write out the steps
f(x) = -2x^2 - 5
f(2) = -2(2)^2 - 5
f(2) = -2(4) - 5
f(2) = -8 - 5
f(2) = -13
