Answer: x = -17
Step-by-step explanation:
4x-13=5x+4
(4x-13)+(13-5x)=(5x+4)+(13-5x)
4x-13+13-5x=5x+4+13-5x
4x-5x-13+13=5x-5x+4+13
-x=17
x=-17
Answer:
Step-by-step explanation:
If the area equals p*q divided by 2 then your equation would look like this,
A= 2.4*16.4/2
A=39.36/2
A= 19.68 in^2
When rounded A=19.7 in^2
Answer: 320 grams
Step-by-step explanation:
Let the mas of the teapot be denoted by a
Let the mass of the cups be denoted by c
The question can be turned into an equation which will be:
a + 4c = 1280 ......... equation i
a + 10c = 2720 ........ equation ii
Subtract equation i from ii
6c = 1440
c = 1440/6
c = 240 grams
The mas of the cup is 240 grams
From equation i
a + 4c = 1280
a + 4(240) = 1280
a + 960 = 1280
a = 1280 - 960
a = 320 grams
The mass of the teapot is 320 grams
Answer:
-6and 5
Step-by-step explanation:
x²+x-30
by factorisation;
(x+6)(x-5)
x+6=0
x=-6
x=5

Im not sure about this one but i think x is 60 since the line Ed basically bisects the angle E which also bisects the line GH in half so that 62=x+2 and then solve for the equation
