Answer:
3 horses and 4 ducks
Step-by-step explanation:
let h be the no. of horses and d be the no. of ducks
h+d=7
d=7-h
Since horses have 4 legs and ducks have 2 legs,
4h+2d=20
4h+2(7-h)=20
4h+14-2h=20
2h=6
h=3
d=4
11 - 3x < 53
First, subtract 11 from both sides.
-3x < 42
Then divide -3 by both sides, and switch the sign.
x > -14
Answer:
c) 14
Step-by-step explanation:
The given equation is .
We need to solve this equation for v, so we multiply both sides of the equation by the multiplicative inverse of which is to obtain;
.
We simplify to obtain;
The correct choice is C.
Answer:
Step-by-step explanation:
Y= -2/5 x -4/1 so the answer is Y=8/5
Answer:
We divided the figure into 1 triangle and 3 rectangles (as shown in attached pic).
Adding up the area of them, we get the total area:
A = area of triangle + area of 3 rectangles
= base x height/2 + length1 x width1 + length2 x width2 + length3 x width3
= 6 x (2 + 11 + 5 - 4 -3)/2 + 2 x 2 + 11 x (5 + 2) + 5 x 9
= 159 (m2)
Hope this helps!
