Answer:
3
Step-by-step explanation:
3 (1.5 - 0.5) = 3 (1) = 3 * 1 = 3. The value of the expression is 3.
Tell me if I'm wrong :)
Answer:
x=4
Step-by-step explanation:
4(3x+5)=6(x+8)-x
Distribute
12x +20 = 6x +48 -x
Combine like terms
12x+20 = 5x+48
Subtract 5x from each side
12x-5x +20 = 5x-5x+48
7x +20 = 48
Subtract 20 from each side
7x+20-20 = 48-20
7x = 28
Divide each side by 7
7x/7 = 28/7
x = 4
Answer:
1) u > 4
2) 7 < u
3) u < 4
4) 7 > u
Step-by-step explanation:
1) subtract 6 - 2
2) add 3 + 4
3) subtract 4 on both sides (8-4)
4) subtract 9 - 2
Answer:
angle 1 is equal to 40°
Step-by-step explanation:
angles 1 and 2 are congruent due to alternate interior angles of parallel lines. This means that 2x+20=3x+10, solving this leaves us with x=10. Since angle 1 = 2x +20 and x=10, solve to get 2(10)+20 =20+20 = 40
Answer:
5 2/3
Step-by-step explanation:
First add the whole numbers (3+2 = 5).
Then add the fractions. Since they already have common denominators, just add the numerators (1+1 = 2) and the denominator stays the same.
Since the numerator (top of the fraction) is smaller than the denominator (bottom of the fraction) and it can't be simplified, we are done. :-)
