Answer 1

Answer: 3x + 4y = 17 (1)
-4x - 3y = -18 (2)

multiply equation (1) by 4 and equation (2) by 3 to eliminate x

(× 4) 12x + 16y = 68 (1)
(× 3) -12x - 9y = -54 (2)
---------------------------------------------Add
7y = 14
y = 2

Replace y = 2 into equation (1) 3x + 4y = 17 to find x

3x + 4(2)= 17
3x + 8 = 17
3x = 9
x = 3

)) A triangle has sides with lengths of 5 inches, 12 inches, and 13 inches. Is it a righttriangle?
yes
no

Answers

Answer:Yes

Step-by-step explanation:

Given

Triangle has sides

length $a=5\ in.$

$b=12\ in.$

$c=13\ in.$

If the triangle is Right angled then it must satisfy the Pythagoras rule

$(\text{Perpendicular})^2+(\text{base})^2=(\text{Hypotenuse})^2$

$(a)^2+(b)^2=(c)^2$

$5^2+12^2=13^2$

$25+144=13^2$

$169=13^2$

$13^2=13^2$

Therefore The given triangle is right angled

Three apples and 2 oranges cost $1.25, while 2 apples and an orange were 75 cents. At the rate, find the cost of 6 apples and an orange. ( please show steps thanks!)

Answers

x - apple
y - orange

$3x+2y=1.25\n 2x+y=0.75\n\n 3x+2y=1.25\n -4x-2y=-1.5\n --------\n -x=-0.25\n x=0.25\n\n 2\cdot0.25+y=0.75\n 0.5+y=0.75\n y=0.25\n\n 6x+y=6\cdot 0.25+0.25=1.5+0.25=\boxed{1.75}$
