Answer:
9 carnations, and 6 roses
Step-by-step explanation:
Let x be the number of carnations in the bouquet.
This means the roses will be 15 - x, since both the carnations and the roses equal 15 flowers.
Write an equation:
.8x + 1.25(15-x) = 14.7
.8x + 18.75 - 1.25x = 14.7
.45x = 4.05
x = 9
This means there will be 9 carnations, and 6 roses.
Hope this helps!
Answer:
y = -12x - 77
Step-by-step explanation:
The standard form of the equation is expressed as y = mx+b
m is the slope
Given the coordinate (-7, 7) and (-6, -5).
m = -5-7/-6+7
m = -12/1
m = -12
Get the intercept b
Substitute m= -12 and (-7 7) into y = mx+b
7 = -12(-7) + b
7 = 84 + b
b = 7 - 84
b = -77
Get the required equation
y = mx+b
y = -12x +(-77)
y = -12x - 77
This gives the required equation
Area is 23.03 and perimeter is 23.47
Two divided by a number yields fourteen would be represented by the equation 2/y=14, and that is not right. So, the answer would be the third answer choice
Answer:
Amina practices the piano for 54 minutes each week.
Step-by-step explanation:
45% * 120min = 0.45 * 120min = 9/20 * 120min = 9 * 6min = 54min
