64 and 28 have a GCF of 4, since 64 = 4 x 16, 28 = 4 x 7, and 7 and 16 have no factors other than 1 in common. Knowing that, we can rewrite 64 + 28 as
4 x 16 + 4 x 7
and then use the distributive property to rewrite it again as
4 x (16 + 7)
Answer:
$32.80
Step-by-step explanation:
For this case we have that the total daily protein consumption is given by:
Now, we find the percentage corresponding to breakfast:
53g ---------> 100%
17g -----------> x
Where "x" represents the percentage of protein equivalent to breakfast:
Thus, at breakfast approximately 32.08% of the total protein should be consumed.
Answer:
(-9,3)
Step-by-step explanation:
6x and -6x cancel, leaving us 12y=36 which means y=3. Then we can plug it back into our equations leaving us with x=-9.
Answer:
40 mph.
Step-by-step explanation:
Hope I helped!
x-5=speed of car B
x=speed of car A
distance=speed times time
(x-5)(4.5)=(x)(4)
4.5x-22.5=4x
Multiply both sides by 2 to get rid of the decimals.
9x-45=8x
Subtract 8x from each side.
x-45=0 9 (A)
Add 45 to both sides.
x=45
Speed of car A=45 mph
Speed of car B=40 mph
