15x + 11x + 8x+5 = 180
34x + 5 = 180
34x = 180-5
34x = 175
x = 5.147
by substitution each value by of x by 5
75 + 55 + 45 = 175
Answer:
-7

Because for dividing one positive and one negative number, the rule is that the answer is going to be negative. So, what you can do is just do 56÷8 which equals 7 then add the negative sign to make it -7.
Answer:
25 in.
Step-by-step explanation:
Since we know geckos are 2/5 of an Iguana's length, we need to find the length of 1/5.
So if 10 in. is 2/5, 5 in, is 1/5.
Now, since the denominator is 5, we multiply 5 in. by 5.
5x5=25 in.
25 in. is the length of an average Iguana.
