Answer:
4. x=10
5. x=15
6. x=20
7. x=4
Step-by-step explanation:
4. 50+4x=90
90-50=40
40/4=10
x=10
5. (2x+60)+6x=180
6x+2x=8x
8x+60=180
180-60=120
8x=120
120/8=15
x=15
6. 3x+30=90
90-30=60
60/3=20
x=20
7. (8x+120)+7x=180
8x+7x=15x
15x+120=180
180-120=60
15x=60
60/15=4
x=4
In miles 365 million miles or 365,000,000
in km, 588 million km or 588,000,000
so
scientific notation=(number less than 10 and greater than or equal to 1) times 10^n
so
we need to move the decimal point 8 spaces to the left
to compensiate for that, we multiply by 10⁸ which will move it 8 to the right
so
365,000,000 mi=3.65 times 10⁸ mi
588,000,000 km=5.88 times 10⁸ km
those are the distances in scientific notation
Answer:
51
Step-by-step explanation:
Multiply 3 2/5 by 15
Change the mixed number to an improper fraction
3 2/5 = (5 * 3 + 2) /5 = 17/5
17/5 * 15
17 * 15/5
17 * 3
