compound
Step-by-step explanation:
because there are two types of sentences joined by or
Answer:
Step-by-step explanation:
1) 2x + y =7 -------------(I)
x - y = 2 -----------(II)
2x + y = 7
<u> x - y = 2 </u> {Now add both the equations. 'y will be cancelled}
3x = 9
x = 9/3
x = 3
Plugin x = 3 in equation (I)
2*3 + y = 7
6+ y = 7
y = 7 - 6 = 1
Answer: a) y = 1
2) Prime factorize 12 , 15 and 18
12 = 2 * 2 * 3
15 = 3 * 5
18 = 2 * 3 * 3
HCF = 3
e) 3
Let's convert both fractions into like denominators, so 6 1/3 becomes 6 2/6, 4 1/2 becomes 4 3/6. Subtract them, 6 2/6 becomes 5 8/6 - 4 3/6, which is 1 5/6.
Joby's plant was 1

inches taller than Pat's plant.
Answer:
We divided the figure into 1 triangle and 2 rectangles.
Adding up the area of them, we get the total area:
A = area of triangle + area of 2 rectangles
= base x height/2 + length1 x width1 + length2 x width2
= 7 x (15 + 2 - 6 - 2)/2 + 8 x 15 + 5 x 2
= 161.5
Hope this helps!
