Answer:
9
Step-by-step explanation:
<span>"If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40. ... <span>If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30."

Because 3 is lower then 5 we round 673 to 67.</span></span>
Answer:
EY = 5.3 cm
Step-by-step explanation:
∵ Δ ABC similar to ΔDEF
∴ AB/DE = BX/Ey
∵ AB = 12 cm
∵ DE = 8 cm
∵ BX = 8 cm
∴ 12/8 = 8/EY
∴ 12EY = 8 × 8 ⇒ 12AY = 64
∴ EY = 64 ÷ 12 = 5.3333 ≅ 5.3 cm
Answer:
The absolute value of x is thus always either positive or zero, but never negative: when x itself is negative (x < 0), then its absolute value is necessarily positive (|x| = −x > 0)
Step-by-step explanation:
<u><em>Answer:</em></u>
Maria's age now is 19 years old
Jose's age now is 9 years old
<u><em>Explanation:</em></u>
Assume that Maria's current age is x and that Jose's current age is y
<u>We are given that:</u>
1- Maria is 10 years older than Jose.
<u>This means that:</u>
x = y + 10 ............> equation I\
2- Next year, Maria will be twice as old as Jose.
<u>This means that:</u>
Maria's age next year = 2 * Jose's age next year
x + 1 = 2(y+1)
x + 1 = 2y + 2 ...........> equation II
<u>Substitute with equation I in equation II and solve for y as follows:</u>
x + 1 = 2y + 2
y + 10 + 1 = 2y + 2
y + 11 = 2y + 2
2y - y = 11 - 2
y = 9
<u>Substitute with y in equation I to get x as follows:</u>
x = y + 10
x = 9 + 10
x = 19
<u>Based on the above calculations:</u>
Maria's current age = x = 19 years old
Jose's current age = y = 9 years old
Hope this helps :)
