13 x 11 = 143.
Is this correct?
Answer:
S=-2
Step-by-step explanation:
I used my calculator and got x=1 y=3
solve for y to put them in your calculator
2.1x+4.2y=14.7
y = (14.7 -2.1x)/4.2
−5.7x−1.9y=−11.4
y=(-11.4 +5.7x)/(-1.9)
then using the ploting tool I plotted them and found where they intersected
Answer:
120 y2
Step-by-step explanation:
The floor consists of a square and a triangle
area of square = 10² = 100 yd²
area of triangle = bh ( b is the base and h the height )
Here b = 4 and h = 10 , then
area = × 4 × 10 = 2 × 10 = 20 yd²
company needs 100 + 20 = 120 yd²
The answer is a.{x | x < -2}. The rule of the calculation of inequation is if the equation divided by the same positive number, the direction of the sign of inequality will not change.
