Set equal to eachother
(2x+1) = 79
Subtract 1 from both sides

To prepare for a bake-off, Clarissa used 560 grams of flour each day for 3 weeks. How many kilograms did Clarissa use in those 3
Sindrei [870]
Convert G to kg
560/1000=.56 kg a day

If the bake off was 5 days
.56*5= 2.8kg... per week
2.8kg*3= 8.4 kg for 3 weeks

If it was 7 days
.56*7 = 3.92 kg per week
3.92*3= 11.76 kg for 3 weeks

\bf 2log(x-3)+1=5\iff 2log_{10}(x-3)+1=5\\\\\\ 2log_{10}(x-3)=4&#10;\\\\\\&#10;log_{10}(x-3)=\cfrac{4}{2}\implies log_{10}(x-3)=2\\\\&#10;-----------------------------\\\\&#10;{{  a}}^{log_{{  a}}x}=x\impliedby \textit{using this cancellation rule}\\\\&#10;-----------------------------\\\\&#10;10^{\cfrac{}{}log_{10}(x-3)}=10^2\implies x-3=10^2\implies x=100+3

How to answer this problem
tangare [24]
<2= 30 degrees since its vertical to the 4th angle.
<1=150 degrees
<3=150 degrees

since angle 3 and the 4th angle are supplementary, which means both angles equal 180 degrees, angle 3 equals 150 degrees.

since angle 3 is vertical to angle 1 it's also 150 degrees since they're congruent.
