Mathematics
1 answer:
zalisa [80]3 years ago
8 0

Answer:

1) I just simply added the numerators because the denominators of both fractions are equal. As the denominators are same , I simply wrote 6 by taking the L.C.M of both denominators.

4)

\frac{5x - 3}{6}  +  \frac{x - 9}{6}

=  >  \frac{5x - 3 + x - 9}{6}

=  >  \frac{6x - 12}{6}

Taking 6 common from numerator,

=  >  \frac{6(x - 2)}{6}

Cancelling 6 from both numerator & denominator,

=  > x - 2

That would be-
f(t)=80t+4
How I worked that out-
f(x)=mx+b
b= the y intercept which is 4
mx= your slope, which is 80t
f(t) is your height

Answer:

x\degree = 75\degree

Step-by-step explanation:

Property used: <em>An exterior angle of a triangle is equal to the sum of the opposite interior angles.</em>

=  > 62\degree + (x + 13)\degree = 2x\degree \\  \\  =  > 62\degree + x\degree + 13\degree = 2x\degree \\  \\  =  > 75\degree = 2x\degree - x\degree \\  \\  =  > 75\degree = x\degree \\  \\  =  > x\degree = 75\degree

I am Lyosha [343]

Answer:

80 gifts

Step-by-step explanation:

Maddison hid 12 of her sister's birthday gifts around the house. If this was 15% of the gifts, how many total gifts did her sister have?

Let the Total gifts that her sister has be represented by x

Hence:

15% of x = 12

15/100 × x = 12

15x /100 = 12

Cross Multiply

15x = 100 × 12

15x = 1200

x = 1200/15

x = 80 gifts

Hence, the total gifts her sister has is 80 gifts

Leila says that 75% of a number will always be greater than 50% of any other number.
Gemiola [76]
That is not correct, it depends on the numbers you are referring to. For instance, 75% of 100 is 75, but 50% of 1000 is 500, so in this case the 50% of a number is higher than 75% of another number. Although, is true that 75% is higher than 50% of the same number always.
