Answer:
40^4 - 324 = 2,559,676
Step-by-step explanation:
First we need to factor the left side of the equation, which is 40 to the 4th power. 40*40*40*40 is 2,560,000, now we need to subtract 324 from it which is 2,559,676.
Answer:
65.3
Step-by-step explanation:
89.10 - [(1.20 × 31)+ (4.90 + 7)]
89.10 - [37.2 + 11.9]
89.10 - 23.8
= 65.3
X= -2
25x+30= -22 -x
*subtract 30 from -22*
25x= -52
*divide 25 from each side*
x= -2
Answer:
k
Step-by-step explanation:
X+5y=4
2x+10y=8
x=<u>-5y+4
</u>2(-5y+4) +10y=8 substituted in the equation for x
-10y+8+10y=8 distributed
<u />8=8 combined like terms (-10y+10y)
0=0
