Answer:
$243
Step-by-step explanation:
81 x 3= 243 I'm pretty sure.
36-39/12-5
31-39/12
31-3.25
27.75
-5x+13y=-7
5x+4y=24
add the equation to eliminate x:
13y+4y=-7+24
17y=17
solve for y:
17/17y=17/17
y=1
then plug in y into any equation to solve for x:
-5x+13y=-7, y=1
-5x+(13*1)=-7
-5x+13-13=-7-13
-5x=-20
-5/-5x=-20/-5
x=4
the answers are x=4, y=1
Answer:
(-4)(3) +(-4)(1/4)
Step-by-step explanation:
The distributive property applies. The outside factor multiplies each inside term of the sum.)
(-4)(3 1/4) = -4(3 + 1/4) = (-4)(3) + (-4)(1/4)
