Answer:
She will need 3 more of every ingrediant.
Step-by-step explanation:
7x3=21 so 3 more of everything
38) -first you have to subtract 4-2=2
-then solve for 2^5=32
-subtract 32-20=12
-and finally multiply 12*3=36
40) -you have to solve for the numerator and denominator first
-the denominator is simple because you just have to do 2^3 which is 8
-to solve for the numerator you have to do what's in the parentheses first (3^4-7^2) which gives you 32
-the equation you should have now is 22+1^3+32 all divided by 8
-1^3 just equals 1and then you just solve for the numerator
-to solve for the numerator you have to add 22+1+32 which gives you 55 as the numerator
-since 55 cannot be divided by 8, your answer will be 55/8 or 6.875
42) -first you have to solve for the parentheses in the brackets so solve for (67-2^6) which equals to 3
-now your numerator should look like this: 2[8+(3)^3]
-you have to solve for 3^3 which is 27
-now you solve what you have left in the brackets [8+27] =35
-multiply 2*35 which gives you 70
-70 cannot be divided by 9 so your answer is 70/9 or 7.777777778

Answer:
y = 0.5x + 4, or y = 1/2x + 4 (if you prefer fractions)
Step-by-step explanation:
y = mx + b (slope intercept form / standard form) ; m = 0.5 or 1/2, b = 4.
m = linear coefficient/slope(denoted by <u>a</u> in a 1 degree binomial)
b = constant coefficient / y-intercept (denoted by <u>b</u> in a 1 degree binomial)
to convert this equation into a standard form equation. You need to isolate y and leave the coefficients on the other side.
0.5x = y - 4
0.5x (+4) = y - 4 (+4)
0.5x + 4 = y
y = 0.5x + 4
Answer:
4 light years
Step-by-step explanation:
(2.4·10¹³ miles)/(6·10¹² miles/ly) = 0.4·10¹ ly = 4 light years
