The sum of two numbers is 77. the greater number is 5 more than the smaller
number. which equation can be used to solve for the smaller number?

o 1) x(x - 5) = 77
o2) x(x + 5) = 77
3) x + (x + 5) = 77
4) x + (x + 5) = 77

Step-by-step explanation:

Let's assume that the two numbers are x and y, with y being the larger number.

According to the statement, , and

By substituting the values, we get:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
