Answer:
Answer is 8 3/4
Step-by-step explanation:
Change the fraction into improper fraction.
-1 2/3 will be -5/3
-5 1/4 will be -21/4
Then multiply both answer

2. Reflected over the x axis
3. Steeper
Step-by-step explanation:
Answer:
x =4
Step-by-step explanation:
x/y = 1/2
(x + 2) / (y + 1) = 2/3
Cross multiply the first equation
2x = y
Put that value for y into the second equation.
(x + 2) / (2x + 1) = 2/3 Cross multiply
3(x + 2) = 2(2x + 1) Remove the brackets.
3x + 6 = 4x + 2 Subtract 3x from both sides
6 = 4x - 3x + 2
6 = x + 2 Subtract 2 from both sides
6-2 = x
x = 4
We call A<span>(–3, 5), B(4, –1), and C(4, y), the triangle ABC.
We have the coordinates of three vectors: AB(7, -6), BC(0; y+1), and AC(7, y-5)
Cause this triangle can be right at A, B or C, we have three cases:
+ Right at A: AB.AC=0 or 7x7+(-6)x(y-5)=0
and we have 49-6y+30=0 or y=79/6
</span>+ Right at B: AB.BC=0 or 7x0+(-6)x(y+1)=0
and we have 0-6y-6=0 or y=-1
Right at C: BC.AC=0 or 0x7+(y+1)x(y-5)=0
and we have (y+1)x(y-5)=0 or y=-1 or y=5
<span>
Then, we have 3 values of y.

Answer:
25 little box will fit in the large box
Step-by-step explanation:
50×30×20=3000
10×3×4=120
so 3000/120=25
