Answer:the number of black tiles that Todd used is 27
Step-by-step explanation:
Let x represent the number of black tiles that Todd used.
Todd has 21 white tiles and some black tiles to make a mosaic. Each tile has an area of 3 square. It means that the total area of the white tiles is 21 × 3 = 63 cm^2
The total area of the white tiles is x × 3 = 3x cm^2
The mosaic has a total area of 144 Square centimeters. It means that
3x + 63 = 144
3x = 144 - 63 = 81
x = 81/3 = 27
Answer:
It's a trick answer. It's 29.125/1. That's what I got.
17 - 6 x 10/2 + 12 =
17 - 60/2 + 12 =
17 - 30 + 12 =
-13 + 12 =
-1 <==
Answer:
-1/2
Step-by-step explanation:
Slope is defined as change in x/change in y.
The x changed by 1/8-(-1/4)=3/8 and the y changed by -4-(-1/4)=(-3/4).
Now, divide the 2 fractions:
(-3/4)/3/8 = -3/4*8/3 = -4/8 = -1/2
Answer: Greatest number is 4. Each would have 4 roses, 9 tulips and 5 daises
Step-by-step explanation: HCF is 4 so
