What is -4x+7=11 with the work and the answer

x= -1. subtract 7 from both sides which gives you -4x=4. divide both sides by -4 and you are left with x=-1

Answer-1

Step-by-step explanation: -4x+7=11

subtract 7 from both sides now the equation is -4x=4 now divide the -4 by 4 so u can get x by itself and then u get -1

step-by-step explanation:

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
