(1) 3x + 2y = 51
(2) 2x + 4y = 54
2*(1) 6x + 4y = 102
2*(1)-(2) 4x + 0y = 48
Divide by 4: x = 12
y = 7.5
Answer:
The points P, Q, R and S all lie on the same line segment, in that order, such that the ratio of PQ : QR: RS is equal to 4:2:1.
Step-by-step explanation:
Answer:
Options (1) and (5) are the correct options.
Step-by-step explanation:
See attachment for the complete question.
Simon's work,
Area of the base = B =
=32.5 m²
Volume = Bh = 32.5(12) = 390 m³
Let's check the error's he made.
Area of the base of the triangular prism
B =
B = 30 m²
Volume of the prism = (Area of the triangular base)×(Height)
V = 30 × 4
V = 120 m³
Therefore, Options (1) and (5) are the correct options.
Answer:
Step-by-step explanation:
You have been given a very useful piece of information. It can be used in many circumstances like shopping or figuring out miles / gallon or all sorts of things that you don't want to drag out a calculator to figure out.
Since you can do the question in any order, you should start with the 50 and 2
50*2 = 100
Now to get the rest of it, just add 2 zeros to -36
Answer (-3600)
Estimation is power.
11/12- 1/6
first find the common denominator which is 12
11/12- 2/12= 9/12
simplify by dividing both numbers by 3
answer is 3/4
