Answer:
TRUE
Step-by-step explanation:
2x + 0.8/y = z – 4
x = 7, y = 0.2, z = 22
2×7 + 0.8/0.2 = 22 - 4
14 + 4 = 18
18 = 18
TRUE.
The fraction 13/25 is equivalent to 52 percent.
To workout this, divide the numerator by the denominator, sum this value to the integer part and multiply the result by 100%, so:
13/25 in percent = 13 ÷ 25 × 100% = 0.52 × 100% = 52%
The three stages that have to do with fluency, progression and automaticity are found in the Number Sense and Operations .
<h3>What is the number sense and operation strand of mathematics?</h3>
This is the part of mathematics that is known to teach the student basic ways to carry out number operations in mathematics. This has to do with representation of numbers as well as solving for the existing relationships in these numbers.
Having a sense of numbers is a very important ability skill that has to be developed early is students to enable them progress in the subject.

#SPJ1
Answer is in the attached figure.
38^2x = 109
Apply lg on both sides
lg 38^2x = lg 109
Bring the power down
2x lg 38 = lg 109
2x = lg 109/lg 38
x = (lg 109/lg 38) ÷ 2
= 0.645
