Answer:
dr. potter provides 54 vaccinations TOTAL (including both measles and polio).
p+m=54
since there are 4 doses of polio and of measles, you have to use a variable to distinguish how many doses were given for measles and polio out of 142 given doses.
4p+2m=142
p+m=54
4p+2m=142
^^system of equation
p+m=54
4p+2m=142
p=54-m
4p+2m=142
(substitute 54-m to the equation)
4(54-m)+2m=142
m=37
(collect like terms, then substitute the value of m into the first equation)
p=54-37
p=17
(m, p)=(37, 17)

Answer:
Step-by-step explanation:
Light is considered to be without mass, but it has energy. According to Einstein, energy can be
equivalently presented as mass. Mass is also affected by gravity, but near planets, this effect is
so small that it can be ignored and so we say that light travels in a straight line.
The above statement does not hold true when light passes near a star. A star possesses a very
high gravity field that bends light such that the change of direction is observed.

Answer:
7^10
When multiplying exponents keep the number the same and add the power
FOr example in 9^3 x 9^7 we keep 9 the same whilst adding the exponents
9^10 would be the answer for the example problem

Answer:
1/3 or 1/5, which is larger? If you divide 1 by 3 the answer is 0.33 If you divide 1 by 5 it's 0.2. Since 0.33(1/3) is larger that would be the answer.
sorry if I make this confusing.
basically divide the top by the bottom to see which is larger. Then compare the fractions.
